Colored overlays are designed to help alleviate reading disabilities caused by visual processing disorders by emphasizing text and giving an illusion that the text is on a colored background. They work by changing each color's wavelength, revising how fast signals are sent from the eye to the brain.
Many schools used pastel coloured paper for worksheets and handouts to alleviate these problems. The use of buff-coloured paper, for example, can cut down on visual anomalies and can support reading fluency and text access. “ The use of colour to treat reading difficulties elicits strong views.
Dyslexia overlays, also known as coloured overlays or tinted overlays, are thin sheets of coloured transparent plastic that can be placed over white sheets of text in order to make it easier for dyslexic people to read. They work by making words stand out.
Studies have found that students with dyslexia may benefit from using different color paper or paper overlays because it reduces stress on the eyes.
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.
Bright white slide backgrounds can make text harder to read; choose an off-white or cream background instead. Text should be dark, with lots of space around the letters. Alternatively, a dark background with white text also works well.
Red is the colour of dyslexia awareness.
Irlen Method technology uses colored overlays and filters to improve the brain's ability to process visual information. In people with Irlen Syndrome, colored overlays can improve reading fluency, comfort, comprehension, attention, and concentration while reducing light sensitivity.
Students may find that using a specific color paper, such as light blue or green, makes it easier for them to read and write. The use of color adds a bit of novelty to the stimulation-loving ADHD brain.

She suggests that the overlays help in making the print clear up (by helping the reader in actually viewing what one reads more easily) and lessening the adversity of the visual perceptual problems like Dyslexia.
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.
The page color is supposed to make text easier to see, not to add any other difficulties. Bottom line, the page color can influence the readability of font, and by using light colors, the reader may find it easier to read for long periods of time and not have as much eye fatigue from glare.

Recently I was discussing with Karen Hope, the co-founder of Dyslexia Victoria Online, how colors help people, with dyslexic issues, retain the spelling of individual words. She said that research shows yellow paper with black text is an effective tool with helping memory.
The 4 types of dyslexia include phonological dyslexia, surface dyslexia, rapid naming deficit, and double deficit dyslexia. Dyslexia is a learning disorder where the person often has difficulty reading and interpreting what they read. It is neither infectious nor brought on by vaccinations.
Dyslexie font is a typeface – specially designed for people with dyslexia – which enhances the ease of reading and comprehension.
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.
But seeing nonexistent movement in words and seeing letters like “d”, “b”, “p”, “q” rotated is common among people with dyslexia. Some commenters on Widell's blog said his text mirrored their experience; others said theirs was slightly different or even more difficult.
The Orton–Gillingham Method
This popular method has long been used to teach children with dyslexia how to read. By focusing on the connection between letters and their sounds, children can assign more meaning to the language and develop better overall comprehension.
Red dye 40 is a synthetic food dye made from petroleum. Research has shown that it is linked to certain ADHD symptoms, such as hyperactivity, and may also cause other neurobehavioral effects in children. People can check for red dye 40 on food labels if they wish to limit their intake.
Red should never be used in the home as children with ASD perceive the color as florescent. Yellows likewise are very stimulating and are best to avoid. Greens, blues, pinks, soft oranges and neutrals can be very comforting. Keeping the colors muted, these tones can quiet the mind and create calm.
