Use dark coloured text on a light (not white) background. Avoid green and red/pink, as these colours are difficult for those who have colour vision deficiencies (colour blindness). Consider alternatives to white backgrounds for paper, computer and visual aids such as whiteboards. White can appear too dazzling.
It is therefore likely that blue light, selected optimally to recruit melanopsin RGCs, will have the greatest effect on improving alertness and concentration and may therefore be the best for remediating the impaired attentional responses seen in dyslexia.
The results show that using certain background colors have a significant impact on people with and without dyslexia. Warm background colors, Peach, Orange and Yellow, significantly improved reading performance over cool background colors, Blue, Blue Grey and Green.
Bright white slide backgrounds can make text harder to read. Choose an off-white or cream background. Text should be dark, with lots of space around the letters. A dark background and white text also work.
White backgrounds: Simple and classic, black text on a white background provides the highest readability ratio. Blues and grays also provide the right contrast and thus work well on white backgrounds. However, avoid using white backgrounds for an entire webpage, which can strain the eyes.
When it comes to color combinations, your eyes prefer black text on a white or slightly yellow background. Other dark-on-light combinations work fine for most people. Avoid low contrast text/background color schemes. If you wear contacts, your eyes have to work harder when staring at a screen.
What should I know about "character colour"? The consensus is that the "non-colours", white and black, and the colours yellow, green, and orange are generally most acceptable.
Coloured overlays, glasses and contact lenses can mostly be helpful for people with dyslexia, visual stress and autism.
Dyslexia is not a vision based disorder but if children feel a (placebo) benefit from using coloured overlays then there is no harm, but they should never be used as the only form of support and certainly never as a substitute for an intensive program of individualised Structured Literacy.
Red is the colour of dyslexia awareness.
For people with dyslexia, total contrast — white text on a black background, or vice-versa — can be difficult to read. Many dark themes use total contrast.
Participants without dyslexia tend to prefer color pairs with a higher color and brightness contrast while people with dyslexia read faster when color pairs have lower contrasts.
Researchers like Jeremy law, Clare Wilson, in their works, state that the overlays might seem to be helpful in sorting out the disorder, but actually, they aren't. They clearly state the reason too – Less engagement of the children during reading might be one aspect where the child would have engaged more with colors.
In summary, the present findings provide evidence that green filters improve reading performance in children with dyslexia through changes in eye movement, which reduce the fixation duration required by the children with dyslexia during reading.
Most will have a preferred paper colour, which may not be yellow. Users with dyslexia, other specific learning difficulties or visual impairments are most likely to find materials printed onto coloured paper helpful. It is an erroneous belief that yellow paper benefits all individuals with dyslexia.
Dyslexie font is a typeface – specially designed for people with dyslexia – which enhances the ease of reading and comprehension.
The dreaded red, a color we've all seen throughout our education. The red marker used to highlight our mistakes is all too familiar for people with dyslexia around the world. Associations have chosen this color to take back its meaning and globally promote dyslexia awareness.
Warm colors such as red, orange, and yellow have been recognized as the preferred colors to maintain learners' attention and stimulate their active participation.
The contrast between the text and background is most important, and the higher the contrast, the better. Dark text on a white background actually has the edge in this case, except for people who are sensitive to light or suffering vision loss. A dark background is ideal for these individuals.
Blue eyes also represent innocence and carefree. Brown eyes are a more mature eye color and represent stability, security and strength.
Yellow light, has been proven effective in protecting the retinas of patients exposed to excessive blue light, since it offers the best contrast.
The colour of your background has very little bearing on both your eye health and productivity. If you prefer dark themes, go ahead. Whatever suits your style of working should prove optimal. As long as halation can be avoided, there is very little evidence to prove eye strain either way.
While dark mode has a lot of benefits, it may not be better for your eyes. Using dark mode is helpful in that it's easier on the eyes than a stark, bright white screen. However, using a dark screen requires your pupils to dilate which can make it harder to focus on the screen.
Cooler colors (blue, green, some violets, and yellowish-green colors) remind us of nature. They bring a sense of coolness and refreshment. They are also colors that move away from the eye but bring a calmness that many warm colors can't.
