Parents Need to Know

Parents need to know that Colorblind is an educational game that teaches color mixing while testing your memory. The game will show you a color to remember, and then ask you to mix red, blue, and green on sliding scales to re-create the color. There are a few options to help along the way, including Assist, which moves the sliders close to their final locations; Skip, which skips to the next color; Recall, which shows you again the color you're trying to match; Show Red, Show Green, and Show Blue, each of which set the corresponding slider to the correct place; and two options to Grade, which give you a letter grade based on how close to the actual color you are. You can only use each option once per game. At the end of each round, the game gives you a percentage score based on how close to the final color you are. With potential access to the OpenFeint network, parents might want to disable that network for young children so that they can't connect with locations and people outside of the game.

What kids can learn


Thinking & Reasoning

  • memorization

Engagement, Approach, Support


Kids will have fun figuring out whether they're colorblind with certain colors, and the game does require an eye for detail that kids should enjoy. The score-keeping, similar to grades in school, may also be motivating for some.

Learning Approach

Kids will practice memorization as they focus on the assigned color and matching it, which is a great brain exercise. Kids will develop a keen eye for detail as they see how little movements on each color scale impact the color. The app doesn't offer any options or levels, though each new color presents a new challenge. 


The developer's website seems to be defunct, but the game is clear enough that a huge amount of support, technical or other, probably isn't necessary. 

What kids can learn


Thinking & Reasoning

  • memorization

Kids can learn how color mixing creates different shades and colors and improve their memory skills. This innovative approach to a matching/memory game challenges kids’ memories and makes them pay attention to details of color as they may not be used to, which adds some fun. They'll see how all the colors at 100 percent creates white, while all the colors at 0 percent creates black. The app tracks scores and grades students on a 100-point scale that many kids will be familiar with from school. Kids can see their score for a specific round as well as their overall averaged score. Colorblind, alhough not incredibly exciting or sophisticated, is fun and could be a great introduction to color theory for kids.

What's it about?

Kids get a color to memorize. When they're ready, they hit "start" and go to a screen with a blank color square, several help buttons, and sliding scales for red, green, and blue. Kids will slide the color scales back and forth until they've matched the memorized color as closely as possible. Help options can only be used once each per eight-round game. After kids click "done," they’ll get their score and see their color compared to the original color and the amounts of red, green, and blue in each.

Is it any good?


COLORBLIND is a simple game that tests your color memory and teaches you how to mix colors using different amounts of red, green, and blue. There are no included instructions, but one play through the game will show how it works. Each game consists of eight rounds, each of which tests your memory to re-create one color. There are several included options to give you hints along the way. This game isn't extensive or sophisticated, but it is well done and is unlike traditional memory games. It also keeps track of your highest percentage score and shows that on the main menu.

Families can talk about...

  • Let kids create new colors and shades with paints. Encourage them to create colors beyond the primary and secondary mixes of red, yellow, and blue.

  • Play a memory game with textures and patterns by cutting two squares of six different fabrics and laying them out like a memory game. Kids can match the pattern and texture by seeing and feeling.
