How does light affect colors?

[rockfish]

Hi Fellows,

Quite some time ago, i have a chat with jeremy from Reef and nature. He told me that for red color corals to color up they need more white light(6500k-10,000k). and for green and other colors they need more Actinic Blue lights.

Anyone have experience in this?

Wat other factors will affect the color?

Post ur views!!

No rite, no wrong..

u need to burn e zooxe in them for e colour ...

but must agar agar shift them nearer to e light

dun over burn them...

white light is for colouring growth..

takes time to observe...

10,000K is for growth

blue light brings out e colour in them...

not 4geting water elements is still e most impt factor....
