Eight key lessons from sumi-e: You can express more with less. Never use more (color) when less will do. Careful use of light and dark is important for creating clarity and contrast. Use color with a clear purpose and informed intent. Clear contrast, visual suggestion, and subtlety can exist harmoniously in one composition. Omit useless details to expose the essence. In all things: balance, clarity, harmony, and simplicity. What looks easy is hard (but worth it).
