Wait until Forge compatibility for 1.8.x is completed. Right now MCPatcher doesn't work well with Forge. Don't worry, Kahr is working on it.
@Kahr: While on this subject, may I request a feature for Custom Colors? For custom biome colors, will you add something that allows a pack maker to specify what dimensions a biome map applies to? Not useful in vanilla so much, but VERY useful when running Forge where you don't want the biome colors overriding dimension-specific colors from, say, Mystcraft for example. Hopefully this won't be too much of a bother to add. Thank you in advance.
Sounds great! Would this include a Forge & Liteloader combination?
