How do I change the color of a sprite without WebGL?

Not really.

There's a few things you can do with some third party plugs, but they aren't an equivalent, and they're not trivial to do.

the easiest way is to use a paint program to make a different coloured version of your sprite and put that under a different animation name... no effects, very cpu friendly - as long as you only need a couple of colours.

You need WebGL to be able to tint images.

Construct 3 also has a built-in color property which you can use to tint objects, without needing a WebGL shader effect.

Thanks, I will try it with Construct 3.
