Where colour is used...

Color-coding is in place in public facilities, museums, exhibition sites, etc., where rooms and areas are divided according to theme colors and full of colorful information displays. At railway stations, train lines are color-coded for direction purposes; route maps and time tables are illustrated with lines and characters in a variety of colors.

What bothers colorblind people most?


- When grilling a piece of meat, a red deficient individual cannot tell whether it is raw or well done. Many cannot tell the difference between green and ripe tomatoes or between ketchup and chocolate syrup! Many others are always buying and biting into unripe bananas - they cannot tell if they are yellow or green, and the matt, natural material makes it even harder to distinguish.
- Some food may look definitely disgusting to color vision deficient individuals: a plate full of spinach, for instance, just appears to them like cow pat.
- They can however distinguish some citrus fruits. Oranges seem to be of a brighter yellow than that of lemons.
- A colorblind person is generally unable to interpret the chemical testing kits for swimming pool water, test strips for hard water, soil or water pH tests because they rely on subtle color differences.
- Many colorblind people cannot tell whether a woman is wearing lipstick or not. More difficult to handle for some is the inability to make the difference between a blue-eyed blonde and a green-eyed redhead.
- Color vision deficiencies bother affected children from the earliest years. At school, coloring can become a difficulty when one has to take the blue crayon - and not the pink one - to color the ocean.
- Bi-color and tri-color LEDs (Light Emitting Diodes): is that glowing indicator light red, yellow, or green? Same problem with the traffic lights...
