I don't know why Corsair have chosen orange. I mean BITD it was OK to mix colours. Some of Gigabyte's boards were yellow green and blue FFS. So having something cool like Mushkin Radioactive was sweet.
However, limiting your market to orange and black is nuts. Why orange? it's not exactly the most used colour in building PCs is it?
The Plats worked in about every rig you could think of, and with RGB lighting things don't really need to be anything else but silver and black IMO.
