Explore the foundations of expressive abstract painting in this six-week course designed to help you build your understanding of core principles, and develop confidence in acrylics and painting non-representationally. You’ll be guided through structured exercises that explore value, color, shape, and composition, while also encouraging intuitive decision-making, mark making, and layering. This course blends instruction with personal exploration. You’ll be invited to slow down, tune in, and respond to what’s happening in the moment, cultivating a mindful and authentic art practice.
Week 1 – Value & Mark Making
Begin with the essential building block of value—light, dark and mid-tone. Explore tonal contrast through limited palettes and experiment with mark making techniques as a starting point.
Week 2 – Color Relationships
Dive into color with an exploration of color mixing, transparency vs. opacity. Work with analogous and complementary palettes to better understand harmony and contrast.
Week 3 – Shape & Line
Play with organic and geometric shapes, positive and negative space, and how they contribute to visual interest. Explore ways to create shape with brushes and other tools.
Week 4 – Composition
Bring together elements of value, color, and shape to explore composition. Work through compositional studies and expand your visual vocabulary.
Week 5 – Guided Independent Work
Apply what you’ve learned to new work with a focus on using the principles and your intuition to guide your decisions.
Week 6 – Editing and Refinement
Wrap up with a session that focuses on editing and pushing your work further.
Please note: This is a cumulative and instructional course with no make-up sessions. If you expect to miss more than one class and are new to the course, consider enrolling at a time when you can attend the majority of sessions.
