They come in all colors except black and variants are added day by day since the continuously create new types and colors in labs, this are called hybrid orchids.
This days it really needs an expert to find the difference between a hybrid and a species. Vanda pictures bring the plant colors to glow especially when the flower is lit from the back, never make a photo from in front with a flash it will come out totally flat.
The best is to visit a orchid nursery or garden and make the pics in late afternoon when the sun is low and shine in, that gives the best back illumination.
