Mastering abstract composition and colour begins with understanding balance, contrast, and visual flow. Focus on how shapes interact and guide the viewer’s eye across the canvas. Use colour theory to evoke emotion—complementary and analogous palettes can create harmony or tension. Experiment with layering, transparency, and texture to add depth. Trust your instincts while refining your technique through practice and critique. Ultimately, abstract mastery comes from merging intuition with intentional design for a compelling visual experience.
