    You see the same thing with sea weed : species that grow in deeper places are red while the ones that grow at the coast line are green. But the cause of this is the amount of light that decreases, so with Nepenthes both factors could stimulate each other. Well I am gessing this, I could be way wrong....

    Mmmhmmmm.

    Phycoerythrin absorbs the greens, reds and yellows. Phycocyanin absorbs blues greens and yellows. These are proteins (flourescent?) that cover up the color of chlorophyll, but it's still there. This allows them to live in deeper environments and absorb more of the diffused light there. Nothing to do with temperatures AFAIK.


    This one time I had an orange macro growing on a shipment of liverock that I had just got, and when I turned the actinics on it flouresced the most vivid beautiful red/orange i've ever seen. Sadly it didn't make it


    I think leaves in fall turn colors as the chlorophylle breaks down/dies, and either the color is the result of this or the color is the color already there but is just masked by the chlorophyll. Can't remember.

    yep. the case with seaweed is sea water absorbs different spectrum ranges the deeper you go. So deep-water seaweed is different colors because, while red-orange-yellow light gets refracted or absorbed at fairly shallow depths, green-blue-violet light penetrates deeper (which is why deep water appears blue). Chlorophyll wouldn't work well in this light spectrum, but red and brown seaweed found a way around it. The Nepenthes aren't experiencing conditions quite that extreme, however..

    the other pigments were already there, but masked by the chlorophyll. they appear as the chlorophyll degrades. I was kinda surprised by that when I learned it!

    It's hard to comprehend for me lol. How such colors can be there but you just can't normally see them.

    but....

    Thanks again. But how can those be applied to temp.?
    Perhaps it's coincident , winter in Thailand means shorter days , longer night
    and cloudy. Thus plants produce less chlorophyll . Sound reasonable ?

    Nong,
    We get the same phenomenon. Our winter pitchers are more intense in color, and we get very sunny days. I believe it has something to do with night temperature drops when the plants are metabolising sugars.
