Drawing a Tropical Fish: Step 6
Apply the dark colors last.
DARK TONES: The sixth step in this drawing is to blend in the darker colors: crimson, blue and black.
TECHNIQUE: The main danger in using dark colors is that you blend them excessively into the lighter areas, thereby destroying the luminosity of the image. The trick here is to work cautiously, starting with crimson as the lightest color, followed by the blue and finishing with the black. The white edges to the fins, which seemed too bright after the dark colors were added, were partly subdued with a pale blue.
