- Use a black and white photo as a reference
(you must have permission to use the photo).
- Pick five different colors.
- Draw your "Colorful Portrait" with these colors.
If you do a Google image search for "colorful portraits" you'll see exactly what I have in mind. https://www.google.nl/search?q=%22colorful+portraits%22&tbm=isch
If you have a color photo you would like to use as a reference, you can turn it into a black and white photo by using the "Color Adjustment" filter and setting "Saturation" to 0.
PS: The "Sktchy" app is probably the best place to find a reference photo for this compo. Twinee1 Jules
