What you did

Load a Greyscale PNG spritesheet (via from_grid), set any colours with blue in them.

What you expected to happen

The blue tint should be applied.

What actually happened

Blue is ignored, producing inaccurate colour representations.

Additional information

Opening the png file and re-exporting it as an sRGB file solves the problem.

The original spritesheet shows as white on black for me. I don't see any blue tint. (using firefox for android)

I probably should have been more clear in my issue description, but this is key:

Load a Greyscale PNG spritesheet (via from_grid), set any colours with blue in them.

The original sprite sheet is white (with a transparent background, not black), but when setting the color option on TextureAtlasSprite to a color with a blue tint, that tint is ignored.

It seems #1524 will fix this though 🎉
