LEDs have a very poor spectral range, and mixing 3 distinct colors (RBG) is not the same as real full spectrum color. It's a good approximation which is why we use it, but an approximation none then less.
- dekhn 4y agoYou're referring to the gaps in https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=3836a https://www.thorlabs.com/newgrouppage9.cfm?objectgroup_id=38... Spectral range in LEDs in the past decade has become amazing. For the visible spectrum you can cover the entire area with a reasonable intensity using just 3 LEDs, although the use case I'm describing is "fully saturated" which is hard to achieve in some areas. Yes, there are gaps and color mixing isn't great. That said, I did build a color-cycling LED night light and it fills the whole area with solid color across the spectrum (I had to switch to HSV to make that work well).
