others will answer this better, voop, but red leds are very easy to make and have been for years from "traditional" silicon materials. The ASP of red leds has always been low and there are many producers. Blue (and white, which is derived from blue) has always been much tougher to make and until recently was terribly expensive. First Sapphire and now SiC have come a long way. When you have Red, White, Blue and Green....well the wonderful world of color is open to you. Now, if your question is instead why CREE does not invest some capital into the growers and technology necessary to create the much more common, lower margin red leds so it can sell a "total product line" to led customers, I would expect it is a business decision based on the fact that red leds require different (and simpler, of course,) technology, would not be assembled the same way as blue or green SiC leds would, etc., etc. In other words, why chase a saturated market when you can concentrate on the seemingly insatiable blue/white/green side of the game? The secret is SiC, SiC, and nothing but SiC.
