The RGB color model is most closely associated with digital displays like computer screens, TVs, and other video electronics. So, naturally, RGB is something those of us that design for digital displays are quite familiar with.

With so many tools and software available at our disposal, designers can get away scot-free without knowing how the RGB color model works. There’s no need to calculate a color’s RGB value, or be able to read RGB color values, because Photoshop will do it for us. But it never hurts to learn the fundamentals.

If you want to practice your RGB color identification skills, head over to the online game called RGB Challenge.

The game is true to its name. This game is definitely a challenge.

The RGB color values you’re tasked to identify aren’t simple colors like rgb(255 , 0, 0) (i.e. red) or rgb(0, 0, 0) (i.e. black), it will be colors such as rgb(206, 61, 61) which — I think, I’m not really sure — is a sort of muted pink.

After five attempts, the best score I was able to muster up was 6. I’m pretty sure you can do better. (Share your best score in the comments.)
