I'm using RPG-Maker-XP-like sprites (any 2D adventure/RPG style sprites). I would like to tint them so that they look different at different times of day.
Times of the day are the set of:
- Daytime (normal)
- Early morning (bluish?)
- Sunrise and Sunset (orangish?)
- Night time (dark)
What do I need to do to tint them, and make them look good, during different times of the day? Are there any "known" formulas for any of these times, like "delete the green blue component and tint heavily red+green for a sunrise effect"?
Ideally, I have just the original sprites, with no additional information or images (like spot-highlights or shadows separated out).
Finally, I'm using Silverlight/FlatRedBall for this, so I do have access to per-pixel information, as well as RGB tinting (adding, subtracting, multiplying, etc.)
