Color variation dependent on time of year

[Tracy]

I have noticed that the emergent leaf color on my Burretikentia koghiensis seems to be more colorful when they open in cooler times of the year, which also coincide with it never getting direct sunlight.  It is similar to the variations in my hibiscus flowers which open with deeper colors in the winter than during summer.  I haven't really paid much attention to see if my Chambeyronia hookeri exhibit this characteristic but thought I would solicit other comments about experience with colorful emergent leaves and variations dependent or correlated to temperature, time of year or sun exposure.

the cause of the color is lack of chlorophyll and presence of anthocyanins(red) and carotenoids(yellow).  I think if the palm isnt actively growing the green(chlorophyll) will be slow in synthesis the leaf .  Low PAR will limit the rate at some point.

Chambeyronia houailou showing about as much color as this one ever does.  The color on this plant tends to be much more  subtle than this leaf opening in mid December, but houiailou's are known more for their shape than the emergent leaf's color.
