It is quite interesting ----- like 'slow and steady' (growing in less light) versus growing at a faster rate. Like ---- slow and big ........ versus .... fast and small.

Flower colour or colour effect probably also depends on light intensity too. Whether grown in low light or high light, there are probably always exceptions. Such as ---- depends on what sort of phal we're talking about.

With regard to Phalaenopsis, consider the habitat of the majority species that are in the ancestry of most hybrids - they grow in warm, humid locations near the equator (substantially equal days and nights all year) on trees in heavy forest - so fairly shady, around 12 hours of soft daylight every day. Growing on trees, they get rained on, then dry out when the rain stops, but humidity is high all the time. The closer we can come to those conditions of light, warmth, humidity, and a wet-dry cycle, the happier our Phals will be.
