It took me a while, but I finally figured out why your color gradients were different in nature to the grayscale gradient.
All of your color gradients use a constant light output. You transition from one fully saturated primary to another, or two fully saturated primaries to two others. For that to look natural, the interpolated values should also produce a constant light output.
The grayscale ramp is not a constant light output, and the light intensity needs to follow a perceptual curve to look natural.
