Prismarine Mod, which was made by Torquebolt, adds tools and armor which can be dyed to your liking and respond very well to the dyes with very vibrant colors. To get started, you can find prismarine deposits generally in oceans. Once this mod is updated to 1.8, the modded blocks/items will be removed (since they will exist already) other than the tools and armor and then expand upon the extra functionality of this nifty new crafting material
