10K bulbs are great for growth, but are terrible for color. The best color temps for a good mix of growth and color are the 14K and 15K, if you are going for colors that really pop and enhance the fluorescence you would want to use 20K bulbs. Same for actinics, if you want color that pops then you would want a mix of 420nm and 460nm actinics, the 50/50 and daylight bulbs add more white light in the 10K - 12K range. It all really depends on personal preference and what corals you are keeping. Another thing to consider is that the type and brand of ballast also makes a huge difference in the actual color temp produced. There are a tn of threads on here to learn about Halide lighting, do a search for Sanjay and Lighting.
