Hello, I'm pretty new to pixel art, and I was wondering how to make colors appear as if they are being seen through glass. I tried averaging the luminosity and hue values for the color of the glass and the color that was going to be seen through it, but kept the original saturation level of the glass color. This seemed to be giving me nice colors until I tried shades of brown, where it turned them green after I tweaked the values. Any help would be gretaly appreciated. And if it can be done, I would much rather receive a method that gives me a mathematical way of getting the color, instead of just "going by eye," because I have no idea what color I should try to get just from looking at the glass color and the other color.

Aw, I was hoping I wouldn't get that answer.   But thank you very much for your reply, I really appreciate it. I guess I'll just have to learn to look for good colors. I'm not sure I want to post the picture yet, I like submitting completed work.

I mean here on the forums.

To be more precise in the Work In Progress section, or WIP for short.

For normal glass, usually there is no visible colouring. Instead try implementing specular reflections of the environment. Example.

Thanks for the help everyone. I think I'll try Monkey's method first, and if that doesn't work, I'll do Lawrence's method and go by eye. And for the ones wondering, the object behind the glass is a part of a city by the river, including a park, small beach, and some buildings.
