Orchid Leaf water absorption

[PapaPhal]

I have what maybe a stupid question but I think I get a reprieve because I am in the beginners’ forum. I am not sure if this is significant or not but every time I mist my plants, particularly the phals, I notice that some of the leaves repel the water; it beads up and evaporates off, and others apparently absorb the water because the water is gone a lot faster. The leaves that repel the water look shiny whereas the leaves that absorb the water look dull. Kind of like the difference between flat and gloss paint. I am guessing that this common but I am not sure. Thanks for your input.
