New 'When Touching Colour _' Block
I was trying to make a project for drawing a sprite with the pen feature, but then I realized that a variable can't fit inside a 'when touching color _' block. If a variable could fit inside the colour square or a new block that instead of a square, there was numbers (like the 'set pen color to _' block) then it would really help & I could make the project!

Re: New 'When Touching Colour _' Block
Color variables have been suggested before. I particularly like the idea of having 24-bit color as red*256*256 + green*256 + blue, which would allow users to actually know what color they were getting and to do various shading tricks. The current "color effect" is mysterious, as the color mapping is rather arbitrary and is never explained to the programmer.

Re: New 'When Touching Colour _' Block
I think that this is a feature still needed. It would add a whole new branch of projects. You could have a paint program that can save any color, a picture taking program (with the new video feature in 2.0), it'll be a very useful feature. But shouldn't it be a reporter block?
(I know this is a topic from 2007, but I really think this feature is needed.)

I agree, we do need this feature
