Watercolor Pro Bundle:

Three in-depth courses that build skills steadily, no confusion or guesswork.

 
JOIN THE PRO BUNDLE

Feeling unsure where to start with watercolor?

The Watercolor Pro Bundle is your perfect roadmap:

1️⃣ Watercolor Fundamentals — Foundations & technique.

2️⃣ Transparent flowers — Learn to layer light washes, and use subtle color transitions so your flowers look luminous, delicate, and realistically transparent.

3️⃣ Expressive Flowers — Go bold with loose, characterful florals using strong contrasts, dynamic strokes, and rich color for your personal style.

You don’t need to do everything at once.

Start where you feel most comfortable and move forward when you’re ready. Each course supports the others, helping you build understanding instead of isolated skills.

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.

Hello, I'm Olga Koelsch!


I'm a watercolor artist, book author, and educator based in Bergen, representing Norway in NAS (Nordic Watercolor Society). My journey with watercolor began in 2016 with a simple set of paints. Within a year, I made significant progress in botanical illustration and participated in key botanical exhibitions across the UK, USA, and Japan. By 2018, I began experimenting with modern watercolor techniques, particularly focusing on transparency and expressiveness, which led to my first custom orders.

Today, I'm a full-time artist, with my work featured and licensed globally, including collaborations with Hobby Lobby, Home Decor, Next, and Karen Millen. I am proud to be a Resident Artist at Arches and an Ambassador for Princeton Brush, Maimeri, Canson, and Daler-Rowney.

As an educator, I've had the privilege of teaching students from around the world, sharing my passion for watercolor. In addition to my YouTube channel and my book, “How to Paint Watercolor Transparent Flowers,” I’ve developed a series of in-depth watercolor courses that have received incredible feedback from my students. 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.

What My Students Say: 

"Started with the Fundamentals course and got water control and basics solid. Then Transparent Flowers helped me master that transparent effect and create beautiful, light flowers. Expressive took it next level with bold, vibrant compositions. I could also apply everything I learned and have fun with it. Perfect bundle progression!"
— Ruth, 44

¨Thank you, Olga! Your detailed, patient explanation finally showed me where I've been going wrong all these years. Not a beginner, but wished I'd had this fundamentals breakdown sooner. Learning the properties of paint ended my frustration. Stunning work, very much enjoying the course!"
— Carolyn, 51

¨This color mixing lesson blew me away, so much to learn! The swatching tied it all together, and Olga's flower color guide is great for matching shades later. Ideal for visual learners like myself.¨
— Linda, 46
