I'm talking about randomizing or setting the RGB values from 0-255. I have a situation right now where I've created many different sprites to achieve the sense of random colours but at the end they all feel very static after a while. WebGL as someone above said doesn't work on all platforms.
There's at least three huge benefits with this.
1. You only need one image. More efficient and smaller sized games in memory and disk.
2. You get true random colours. Reduce the effect of a static and boring impression from a player perspective.
3. Less work in creating and sorting each image for each colour.
It doesn't feel that this should be hard to implement in the software, correct me if I'm wrong.
