Very healthy anemone however....

Some of you will have seen photos and videos of my magnificent magnifica anemone. It's done great from the day I introduced it and is doing and growing well. The nem is a host for my pair of common clowns who love to play in its tentacles.
Here's a video taken a day ago.

I have no real issues with my nem far from it however, I do have an observation and a question somebody may be able to assist with.

Firstly some specs about the tank setup.
The tank is a D-D 1500 pro reef.
Lighting. I have 2 x Orphek icons. 3 x Orphek 120 light bars which are 2 blue plus and 1 day plus.

More recently I suplimented the above with 2 x Lominie Asta 20 6500k daylight cob lights which have been replaced by a Kessil 160WE freshwater cob type light. I am currently experimenting with the colour and power of the Kessil.

OK now for the issue/ observation.
When I bought the nem is was a dark purpleish colour with cream tips. Over the coming weeks the colour substantially lightened as can now be seen in the video.

I added the 6500k lights replaced with the Kessil which so far has not made any difference to the colour of it but it does enjoy the extra daylight spectrum provided.

I clearly have more than enough light and thought with the current lighting provided the nem would darken back similar to when I bought it.
My thinking being more intense lighting = darker the colour due to the Zooxanthellae but so far it's not working that way.

Don't get me wrong it's a nice colour but it would be even nicer if it darkened up a little more.
Maybe I have it the wrong way round and the stronger or better the light the lighter a magnifica will become.
Any thoughts?

It's a really nice anemone!

Thanks, You're not wrong.

If you're talking about how the cream colored tips take up more of the tentacle, this is normal, the tips get very tiny when the anemone is not treated well, and they are longer like this when they are very healthy. It will not likely be any worse though, this is about as much as I have seen on any of my anemones.

When you have high light and low nutrient in the water, then the concentration of zooxanthellae in the tissue of the anemone is less. The over all the brown color is lighter. However the actual coloration of the anemone is more intense; the tips are whiter and the coloration of the body/foot is brighter.
Less light and more nutrient in the water will result in darker brown color due to the increase concentration of zooxanthellae. The coloration of the anemone is duller, less white tip and body color is less bright. If the light is too low to substance zooxanthellae then they start die off. In this case the anemone a light bleached anemone, dull translucent anemone with minimal tip coloration and body coloration.
Regarding nutrient affect, high nutrient level will result in high zooxanthellae concentration and "brown out " of the anemones or corals. These are just generalization of the affect of nutrient and light on coral and anemone coloration as a whole.
This is very similar to SPS and LPS coloration variation due to light/nutrient.

Nope not the tips in fact everything but the tips have gone lighter.

Thanks, My nuitrents are quite high at the moment around 50ppm NO3 and 0.2ppm PO4. Colours of my LPS and SPS are fine.

What’s the PAR? I’ve noticed coloration getting more intense under strong light, and I don’t mean strong by SPS standards, I mean 400+ PAR. Anecdotal, of course, but IME. Btw my mags are under 400-500 PAR and low nutrient (1ppm no3, .05-.1 PO4) conditions but are target fed regularly.

Sorry I have no means of measuring PAR. However, given my lighting it must be high.
