I'll be happy to show more pics when fully open abax! I took a pic about 20 mins ago or so - and we get to see an early preview. The buds of this one have been developing in full sun - so quite warm temperatures during development. And it looks like when the temperature is warm, the lip rim doesn't get the pinky colours.
But I think if I allow the buds in the shade, and not let the buds get too warm, then the flowers gets some colour on the rim too --- like in this pic here --- (which is from a different plant, but same clone - buds developed with cool temperature) ----- getting a pink gumball bubble effect hehehe

The pic below is the one taken about 20 minutes ago. The colours are much nicer when seen with the eyes. The green-lime colour is really quite flourescent when we watch with our eyes. It's much more sparkly or glittery when seen with the eyes, even though the camera does show some bright bits from the sparkles.
