The one that did it just forgot that the original color scheme was orange on black and blue on black.

The 10S calculator uses the same orange and blue, but it is on an all-white background and the captions are written above the keys, not on them. I have no difficulty using the 10S in work.

I'm not colour-blind but I agree that the final choice is bad - even I have difficulty distinguishing the orange letters, especially those on the number (grey) keys.
