Colours are fine.. Either way works although for my sensibilities the red works for the Delete button. I am red/green colourblind and the two have distinct enough values that I can easily tell them apart. But I think YES and NO shouldn't be there. It's an extra piece of information that demands the original context of "Do you want to delete this album". It might seem like a small mental investment to ask of your users but people have varying degrees of comprehension at different times, whether due to temporary distraction or because of more permanent conditions such as dyslexia and such. Instead I would just say "You are about to delete this album" And have the buttons read "Cancel" and "Delete"... Or something similar. Undo would also be preferred as comex mentioned.. Or even better a git-like revision history so you can undo any action in the past. This comes with other technical challenges I'm sure but it's the most powerful solution.
