This video talks about the quality of spectrum from various LED light sources and why it matters. IIRC they suggested amber LEDs in addition to white. https://youtu.be/5U-F7EhLp7g

Really interesting.. would be great to see photographs of the effect of illuminating subtractive-colour pigments with this system.

Thanks, will try to take some in the near future.

Thank you, I will definitely look into this.

That's what Philip's Hue system uses for it's color bulbs, a 5 color system. Third-party systems are usually referred to as RGB+CCT. I got some pretty dense strips from superlightingled for my recent kitchen lighting project, which were nice since they had all 5 colors on a single chip

This is timely, since I’m currently fiddling with an RGBW LED strip and having trouble mapping HomeKit’s HSL values.

Thanks for that information, was searching for "RGBAW" and got not that many results ^^

Yeah, you can sometimes find them under RGBWW, RGBWCW, RGBWWCW. This was the strip I went with for my lighting: https://www.superlightingled.com/dc24v-rgbcct-5in1-480leds-u...

These are available in 12v: https://www.superlightingled.com/single-row-rgbcct-5in1-seri...

Keep in mind, a lower voltage for the same light output means more current, so if you're doing a large build, spec your wire gauge accordingly.
