Some of us have this experience with our orchids: when we bought the orchids, the flowers are intense blue or pink, but in the subsequent blooms, the orchid flowers are no longer the same color. It's a little deceptive, isn't it? The reality is that a lot of orchid flowers are dyed!! Growers injected the flower dye at the base of the spike. Most likely, the original color of these orchid flowers are white (easy to dye). There's no way for you to achieve the same intense blue or pink again, unless you feed your spike with dyed water too. But I always like my orchids natural. Knowing where the color came from, the dyed version never attracted me. How can you tell if an orchid has been dyed? They do have a certain look to them. The color may not be completely even, and each flower has a slightly different shade to them. Also, you may be able to find a tiny hole at the base of the spike where the dye was fed. Also, if you find a blue Phalaenopsis, then the likelihood is that the plant is dyed. There's no naturally-occurred blue Phalaenopsis (yet); they are only somewhat purplish blue. Therefore, if you see a really blue Phalaenopsis, it's not natural.
