I would like to make a render that consist of a glossy black room with some white letters (being the only lights). However as this looks fairly bland just being monochrome, I was wondering if I could change the emission light to a light blue without changing the color of the text model. I got fairly close to the effect that I desired by using two emission shaders (one white with strength 1, other blue with strength 5) feeding into a mix with a .9 split, but the text was still more blue then I would like, and I couldn’t get the brightness just how I wanted it.
Perhaps something like this:
For camera rays the bottom Emission shader is used, for all other ray types the top one.
