I need to figure out how to use a single specific color for translucency. I have read some articles on translucency, but they require you to use two images for the translucent effect. I know that in Doom, a bluish-green color was used on images where a translucent effect was needed. How could I use solid black (R0, G0, B0) for translucency in my game? I am unfamiliar with palettes (PAL files in Doom), but I am sure that it had something to do with the translucent effects. Thanks to anybody who can offer me some assistance with this.
