This is the best lesson on color mixing, I learned so much. The color swatching brought it all together for me. I love your little book of colors for various flowers, what a handy resource. I think it will also be helpful when I want to recreate some of the colors. I am such a visual learner, this was excellent.

Olga teaches so well, breaks everything down simply. The course built my confidence and got me loving watercolor again!"

I want to thank you so much. You explain things in such detail, demonstrating patiently all the while, I am not a beginner but I am wishing I had someone like you to help me understand where I so often went wrong and why. Learning through making mistakes is valid but without understanding the fundamentals, that method of learning will always bring frustration. Your work is stunning and I am very much enjoying this course.

Hello, I'm Olga Koelsch!

I’m a watercolor artist and educator based in Bergen, proudly representing Norway in NAS (Nordic Watercolor Society).​

My watercolor journey began in 2016 with a simple set of paints, and within a year, I was showing botanical illustrations in prestigious exhibitions in the UK, USA, and Japan.​

In 2018, I began exploring modern watercolor, focusing on transparency and expressiveness, which quickly led to my first custom commissions. Today, I’m a full-time artist with work licensed worldwide, including collaborations with Hobby Lobby, Home Decor, Next, and Karen Millen.​

I’m also a proud Resident Artist at Arches and an Ambassador for Princeton Brush, Maimeri, Canson, and Daler-Rowney.

As an educator, I’ve created in-depth watercolor courses that have received amazing feedback from students around the world. Your progress inspires me to develop easy-to-follow yet comprehensive classes that empower you to paint with confidence, offering a solid foundation of skills to support your creativity.
