Color Blind Pal allows people with color blindness or color deficiency to see the colors on their screen more clearly. It also lets developers see what their screen looks like to someone who is color blind.

The Color Selector feature shows the color at your cursor, including a descriptive name like "faint green". It tells you what the color's hue, saturation, and value are, so you'll know exactly what the difference is between, for example, "teal" and "cyan".

The Color Window feature isolates a color of your choosing so you can see what parts of your screen are that color. For instance, you can look at a picture of a sunset through the Color Window and cycle the selected color from purple to yellow to see exactly what colors are where. You can use the Shift feature to change the hues that are harder for you to differentiate to easier colors, based on the color blindness type you select. This feature can also be used to simulate any form of color blindness.

You can easily open and close the Color Selector and the Color Window with keyboard shortcuts or a menu bar icon.

With Color Blind Pal, you can easily do the following and more:
  • Find out exactly what any color is
  • See all the colors in any image
  • Read any color-coded map, chart, or graph
  • Pass a color vision test (it turns out there really are numbers in those dots!)

    To get the full help of Color Blind Pal, you can upgrade to Color Blind Pal Pro. This upgrade gives you access to the most powerful features available.

    The Stripes feature in the Color Window draws a striped pattern on selected colors, like red. This feature makes it natural to see whether a color is red or green while still preserving the actual color.
    The Color Portal lets you apply the Color Window to your whole screen while still directly interacting with the windows behind it. Never work without color vision again!
    The customization features let you personalize Color Blind Pal. You can turn on developer color codes for the Color Selector, change the color names to "scientific" or "colloquial" with different color name packs, set your own keyboard shortcuts, and customize the Color Window toolbar.

    With the Color Blind Pal Pro upgrade, you can do anything that someone with full color vision can. Don't be held back by color blindness ever again!
