General Chat

5EXY, So in future we should all just answer YES or NO when asked a question

This is a general chat board and not a survey with tick boxes to give a yes or no answer and the OP never stated that a yes or no answer was the only option and the OP never asked for only members who have epilepsy to comment so their for it is open to debate,

You have posted several times on this thread with your input and point of view

I as do others have valid points of view/input and i will post my opinion whether you like it or not

Roy

The question was not what colours are used in Printers, Computers or screens, The poster of the thread asked

JUST ASKING IF THE BRIGHTNESS WOULD AFFECT
CERTAIN TYPES OF EPILEPSY?

I have to say YES it does

My take on this is basically the same as you Rollo,

Large companies often like to maximise profits by making staff work on a shoe string budget and not enough staff for the work load

Been their done that and got the T shirt to prove it

The elements of an LCD screen are red, blue, green. There is no black. White /black uses the polarity of the pixels.

The color space of an LCD screen is rather less than that of a typical CRT flat screen (24 bit v 32 bit color space) which is why professionals stayed with CRT a lot longer than office / home user. Professional 32 bit LCD is now available, at a price. Either way monitor color space is way less than the human eye and a lot less than paint or advanced printing. Monitors which are calibrated to support Pantone printing will be well out of your budget comfort zone.

LCD brightness is a lot less than CRTs which is why they are so useless in sunlight. There is no real fix for this. Mobiles / tablets are moving to other screen technologies.

Human perception of "sharpness" is largely a function of color depth rather than pixel resolution. That is why 1080i TV at any distance beyond a few feet looks little different to 720. As I have posted Microsoft make use of this to improve font sharpness using "ClearType". If you have XP make sure that clear type is enabled.

Given that most people now use LCD and they are (a lot) less bright than CRT why the wailing about too much white on Gru? Well human vision is very subjective. Contrast is not seen as an absolute thing but relative hence pale turquoise on white was pretty well certain to raise a cheer (not).

Changing the brightness setting of the LCD monitor is a waste of time as the contrast ratio will be unchanged. However it does help to ensure that the screen is properly set up so many run with the factory default ...

What can make a difference if you encounter such a problem and are unable to impose a different CSS is to change the gamma settings. You can do this with the control panel screen settings.

That Gru claims that the proposed color scheme was ok on a walk through was unfortunate to say the least. There are plenty of software tools with which to measure proposed web designs for color / contrast acceptability and well defined standards too. These have been ignored.

A sort of fix has been implemented but is inconsistent. An analysis of the Gru DOM color scheme suggests little if any project management (it is chaotic).

Under current UK / EU law Gru has a legal duty to ensure that its product is as accessible to anybody with impaired vision as the normally sighted. This includes the old (who tend to suffer from "floaters" and find flat white nasty), those who suffer from migraine and epileptics. Moreover this duty also applies to people unable to use the mouse who depend on the keyboard. Gru do not have to develop themselves suitable add ons but they could and should facilitate standard add ons such as screen styles, screen readers etc. which they have signally failed to do.

I suppose if Gru made cars you could have any color you liked, so long as it was black. As they don't you can have off white. There is no technical problem in offering users a choice of color schemes so I guess that it is corporate (12 people corporation) that we all have the new house colors.

My take is that Gru are woefully understaffed. They are trying to do all the right things but are running against the tide.

Way to go Gru.

Neubie, Who's arguing? i thought it was a debate and i too have C&G qualifications and working with colour, I worked for ICI colour matching for the car industry and yes it was also a very long time ago but their are things you never forget,

Just hope GR continue to work on getting this problem sorted out for all users

Roy

Roy , I am not getting into an argument about the true colour of white.
I am just relaying what I was taught as a City and Guilds Printer during my training.
I could list a load of site references but as you rightly point out , people are finding the new design uncomfortable .
I also even now find the contrast too extreme , ten minutes and I have to look away. I don't have any visual problems , so for those that do it must be really user unfriendly.

White is a color, the perception of which is evoked by light that stimulates all three types of color sensitive cone cells in the human eye in nearly equal amounts and with high brightness compared to the surroundings. A white visual stimulation will be void of hue and grayness.[1]

White light can be generated in many ways. The sun is such a source, electric incandescence is another. Modern light sources are fluorescent lamps and light-emitting diodes. An object whose surface reflects back most of the light it receives and does not alter its color will appear white, unless it has very high specular reflection.

Since white is the extreme end of the visual spectrum (in terms of both hue and shade), and since white objects - such as clouds, snow and flowers - appear often in nature, it has frequent symbolism. Human culture has many references to white, often related to purity and cleanness, whilst the high contrast between white and black is often used to represent opposite extremes.

Neubie, I am not experiencing problem with the screen glare

Since GR changed it i have had no problems with the white background on GR

I never said that white was a shade,

I said that their are 25 to 30 thousand shades of white ( Fact )

I know that white is a colour and needs other colours to be added to acquire another shade but they are as i said different shades of white just as their are different shades of green or black all of which will either reflect or absorb light in different ways depending on their environment

I have no idea about how colour works within a computer screen but as i said before when this new makeover was introduced it was far to bright for me the glare was unbearable but GR have changed it and i personally don't have that problem any more but others obviously do

Roy

PP
the colours generated by the computer screen are what is called 'aditive light'
the colours generated by printing is called subtractive light.
The colours used on a computer are red blue green and black .. not yellow as I originally said, sorry its been a long time since I studied this..
What you are experiencing is screen glare off the covering of your PC screen.
Also white is not a shade.... fact , to obtain shades of white you have to add extra of one other base colour
white either absorbs all colours of the spectrum and reflects them equally , as in printing or generates all colours of the spectrum equally as in computer screens

Edit
RR def a bit of a blue hue on here ;-)

I'm not finding it any whiter than Facebook but I think the turquoise lettering should be in bold. That would help, I think.

It's not as bright as it was a day or so ago.

Gwynne

According to my paint chart ( well known make ) this is slightly lighter than "whisper of soft khaki" ( under green shades) , or "Hillstar' well known DIY store's own under 'soft whites' . :-D

White is White

NOT so

Their are around 25 to 30 thousand shades of White (Fact)

Several colours will reflect light but White is by far the most reflective colour of all,(Fact)

It's the reflective aspect of the White on GR that is the problem

Roy

Hold a piece of white paper up next to this screen.
The paper is reflecting the light around you , the computer is generating white.Huge difference
Printing uses Cyan Magenta yellow and black because it is reflective light that creates the colours. Computer screens use green red yellow and black as it is projected colour.
I personally think the contrast is way too strong plus the turqoise vinette either side of the page is too fine . I can see waves in mine.
Perhaps this is the cause of the problems people are experiencing

AFTER ALL THERE WAS

A WHITER SHADE OF PALE

ROSE & BC GOT POOTER PROBS ,WELL NOT PC PROB BUT SO MUCH CABLE CONNECTION ONLY RUNNING AT MAX 2 WHATEVER THAT IS
IT WONT LOAD YOU TUBE TAKES TOO LONG :((((

:-D :-D :-D

SYLVIA,
THIS THREAD WAS ABOUT A PARTICULA SUBJECT RE COLOUR AND EPILEPSY AND AS FOR WHITE

IF YOU BELIEVE

WHIE IS WHITE

MAYBE YOU HAVE A VISUAL PROBLEM

"White is white ...lol..this is no different from any other WHITE , ."

- Sylvia, try choosing a tin of white paint; there are many variations of white :)
And one can see from the post in the announcements board that GR are attempting to resolve certain issues; GR staff have accepted that there are issues that need resolving.
