We've talked about starting small and working bigger - but this time we're going to start tiny. Color is challenging to work with, and much of the instruction on Ctrl+Paint is done in grayscale. If you want to start working directly in color I recommend the 'tiny study' exercise. When you're looking at a photo filled with rich details it's tempting to re-create each pebble and tree. This exercise forces you to simplify what you're seeing, skip the details, and only paint the colors. Even though the end result won't impress your friends, it helps hone your eye for color and builds a foundation for landscape painting.
