I've not seen the blue ones yet but I know the dyed ones are sold in the UK because someone at work was disappointed when they paid a lot for one then it turned white at the next flowering
Welcome aboard!
Don't worry about your Phal, it will be beautiful when it blooms again for you. The trick now is to see f you can get it to flourish and spike for you.
Many people buy these Phals, but are unaware that they have been dyed. There's unscrupulous people even in the orchid grower ranks, I'm ashamed to say. Anything for a dollar.
Yes it looks to be a dyed Phal. As others have said it's injected into the spike, and I have a memory that it's some sort of silver solution that gives the blue colour in the flowers.
It should be a lovely white phal with yellow hints on the lip when it blooms again
