One of the toughest aspects of creating digital art is grasping how computers produce different colors. Mixing red, green, and blue light is quite different than mixing colors of paint. However, choosing colors via RGB values is fundamental to working digitally.

This exercise will help you intuitively feel how red, green, and blue light combine to create the entire gamut of visible colors. We will also explore the opposite of additive RGB color mixing: subtractive CMY (cyan, magenta, yellow) color synthesis.

There’s a nasty little problem that happens when you use hardware-accelerated textures to render sprites in a 2D game. The edges of your sprites, which look nice and clean in Photoshop, take on unsightly “ghost” outlines when the sprites are scaled, rotated, or drawn at non-integer coordinates. The outlines are fuzzy, blink in and out, and are painfully distracting! I ran into this problem in our first game, Cash Cow, and only now have I found a consistent way to fix it.

DarkTree Textures from Darkling Simulations is one of those hidden gems of the graphics world that has permanently changed the way that I create art for games. Using a sublime blend of art and mathematics, DarkTree Textures allows you to create images and animations that would be virtually impossible to create by hand. I commonly use DarkTree textures to create special effects like flames and smoke. This tutorial will introduce you to the power of DarkTree by showing you how to create a simple but effective explosion animation.
