What I know..

The Primary colors are...RED BLUE YELLOW
The Secondary colors are.. PURPLE ORANGE GREEN
You can create secondary colors by mixing certain primary colors together. Like blue and red making purple and red and yellow making orange. Some complimentary colors are yellow green, blue purple, and orange red. You can emphasize colors by making the darker or brighten depending on the ways you want to express it. If making shadows you would make a darker area around the place that is the shadow. To make and illusion you would take lighter colors and show the lighter areas of the picture. To make objects on your painting far away you could either make it smaller or the father away from everything else. First you would sketch out your idea on the canvas and figure out what you want to do. Getting your ideas out first and then working your way up by doing the lighter colors of the painting first of the darker colors. Then finally finishing with your final painting something beautiful!
