Which Color?

Hello, which color do you guys think would look good. The UI buttons will be similar to the start button.

 

Depends on what the color palette is for the rest of your game and what the rest of the art style is. Now as far as opinion, the pink or purple. The reason is that the button stands out a little better than the other colors (especially the yellow which is very hard to read).

 

Purple wins for me.

 

Ok, Thanks. The Background for the game is all of these colors which you move past by.

 

Ok, thanks!

 

This may assist you in finding a good colour palette.
