Seems like a clear enough intent to dedicate to the public domain, along with a permission to deal freely.

If not then I think the r and b values are probably fixed and the only thing remaining is the g value. Not sure if that's enough to make it copyright. It might depend on what exactly those values are. I don't know enough about colour spaces and whatnot to say for usre. You could always ask the relevant redshift copyrightholder and see what they think. Ian.
