I'd recommend a mix of RGB and 6500K LEDs for optimal growth. The RGB ones can enhance colouration, while the 6500K ones provide the necessary spectrum for plant growth. Experiment with a ratio that suits your aesthetic preferences and monitor plant health.
I have been buying my lights from this website called
leds.to they have a wide range of products, and the best part is that they have a blog part on their website which gives a ton of info. You should check their website; they may have a better answer for you.
