GDevelop uses lots of different colors on its icons. Some icons are pale, some are bright. Some colors are muted and dull, others vivid and saturated. The buttons to open object and object group editors are slightly less saturated and more pale, while the other icons here are a bit more saturated and more vivid.
I’m testing those out. The problem is, they have to work against all sorts of different background colors. Here are the light blue base colors:
1: Pale colors
2: Bright and saturated colors
3: The blue used in the new GDevelop logo
The dark purples are easy, in comparison. There’s only one hue of purple. Here’s a quick comparison - note that all of these purples are the same, they’re just seen in pairs, against different backgrounds.
All the icons currently use a darker shadow on the bottom left corner. I might leave that out for some icons, like undo and redo, that don’t have smaller shapes where just parts of the shadow are visible.
It would also be possible to change the strength of the shadow on these icons. I think the current setting is fine. Also, hue is a very minor design decision, so I think I’ll just go with pale blue number 3, the one used in the new GDevelop logo.
