Wow Annemie, this is such a cool and clever idea! There is features like this on computer apps like photoshop but I've never seen a real life version! This would be really helpful for doing realistic drawings to make the colours perfect. Your drawing is really good and so clear, I love how you have drawn the Magic Pen with all the possible colours it could be. I would love to see some more of your ideas soon - keep inventing Annemie!
