Excellent game with one complaint

I am addicted to puzzles and finding good ones on the App Store can be a pain but this suited my needs perfectly! I'm an artist and love colors, this helps me understand them even more I think. The component of solving a puzzle makes it all the more great!

I have one issue though, dark values are next to impossible to see. It makes it much more difficult and not in a "that's part of the challenge" way. I wish there was an option to change the background color, maybe to white or a soft pattern or something to help stand out a little more.

The animations of the level select are kind of annoying too, and it's hard to see. The game seems a little... Small? There's plenty of space too so I don't see why it needs to be like that. Maybe I need to rotate it to landscape but that's more or less just a bother to me.

Organizing paint chips- FYI, works on iPad mini!

This feels like arranging paint chips from light to dark or vice versa. Then opposites on the color wheel come into play. Still a beginner in both this version and blendoku2 - can't believe the world records are so high that I beat them ? Something is just wrong with that!

Agree that I would like to see it larger. I have poor eyesight but can still discern gradations so I like both versions. Also agree that navy blues and other dark colors can be difficult to discern against dark background, skip those...

Kudos to developers for thinking this up - and allowing you to just skip the ones you don't get, occasionally very frustrating but mostly fun so far. If you like "flow free" you will probably like this and vice versa. Enjoy! And improve the goofy world record numbers as they are meaningless so far.

Pay $2 to get rid of noisy ads, then pretty addictive

I was unhappy with the free version of this game. It's supposed to be relaxing and pleasant to arrange the colors in a pleasing pattern, but there is always some conflicting color from the banner ad that runs across the top of the game at all times.

I wanted to pay a dollar to get rid of the ads, but you can't do that. Instead, you have to pay two dollars, and decide what level of difficulty puzzles you want to purchase.

I also question whether the "correct" solutions are actually mathematically "correct," in some way, rather than just some guy's opinion.

I checked the red/green/blue values of a couple of the screenshots shown in the App Store. Sometimes, the sequence is a perfect mathematical progression through the colors. Other times, there are strange numerical jumps that might "look good," but don't seem to be objectively "correct" in any way.

(I haven't tried the same test using hue/saturation/lightness values.)

That said, the game is pretty addicting once you get rid of the ads, and adapt to your brain to the game's way of thinking. So I'm increasing my reading from three stars to four stars – addicted, but still annoyed by the peeves I listed above.
