As you can see, a yellow and then its complementary, purple, have now been added. Just as the red was painted in response to the photo, so yhe yellow was painted in response to the red lines, and the purple in response to the yellow.
Sure, it looks rather like a mop at the moment, or maybe a mutant spider. Or even that a snail crawled through some paint. But, once again, remember the aim is to get you going, this is not intended to be the final painting.
