Why moving object in animation or cartoon will have a lighter color compare to solid surrounding color?
Instead of drawing each frame from scratch, animators save time by drawing the background once, then laying the characters and other moving parts on top of it. The characters are drawn on transparent sheets. For each frame, they lay the sheet(s) on top of the background, take a picture, and then move the sheets for the next frame. If there’s a pile of rocks and only one rock needs to move, they’ll put all the other rocks on the background layer so they don’t have to draw them repeatedly. So, what you’re seeing here is a visible difference between the background layer and the foreground layer. There could be a few reasons for that. They could be drawn by different people, using different inks. Or it could be that the background is drawn on paper while the foreground is on plastic, and even if they use the same ink, it looks different on different surfaces. This problem can be avoided, for example by figuring out how much darker the foreground inks have to be to match the background. But
