Nice to see you have jumped in my friend. Ok, you made a mistake {that wont happen again
} Has for the colour difference {Saturation} sometimes this huge difference is down to the coating on the card/paper - there's NORMAL and BRIGHT WHITE, the latter giving a stronger colour output. The thickness of the card can have some impact too, but usually the coating plays the biggest part. Great start all the same ! I will follow this build with great interest mate.
