With over 30 years of experience, Sarah Spiers is the Founder of Chaulk Education and a highly sought-after Educator. Sarah is offering a deep dive into the real science of colour, how it’s made, how we see it, and how stylists should interpret it, with her two-day immersive masterclass.

The Science of Colour

Sarah’s approach looks at the differences in hair structure and texture, the chemistry of peroxide, pigment composition, and the physics of colour perception. Importantly, Sarah has implemented a brand-neutral approach as she believes that stylists should not be confined to techniques tied to specific brands, as true mastery of colour cannot rely solely on product-based training. By adopting a brand-neutral stance, Sarah addresses a common issue: stylists are often taught methods that only apply to one manufacturer’s products, making them vulnerable when they switch salons or when product formulations change.

“Colour is colour. If you understand the theory, you can use any product with confidence. I want stylists to walk into any salon, pick up any tube, and know exactly what they’re doing and have full creative freedom without limitations,” – Sarah.

Designed for Discovery

Day One: Starts with hair analysis, diving into texture science, how coily hair differs from straight, and what that means for colour. From there, it’s a journey through formulation chemistry: understanding peroxide, pigment families, and colour types, permanent, demi, semi, and beyond.
That evening, participants wind down with movement and mindset work led by Maxine from The Max Effect, helping recalibrate their nervous systems for the intensity of the next day’s learning.
Day Two: Brings a deep dive into colour perception, light theory, and how our eyes and brains interpret colour. It also deconstructs the pigment families’ brands use, from natural to synthetic, and explores how to test, identify, and apply them more effectively.

“The way one stylist sees colour is completely different from another. Even the language we use to describe colour creates different images in our minds. My job is to help people become fluent in their own colour language,”– Sarah.

Collaboration, Confidence, and Content Creation

Mindset coach Cristina Fazzone helps attendees embed what they’ve learned through confidence practices and cognitive frameworks. A professional photographer gives hands-on insights into lighting, colour reflection, and content creation, bridging the gap between artistry and digital storytelling.

Youth Lab’s representatives will be present at each event, showing how simplified scientific models can make advanced concepts click in seconds. Adding to the excitement, the YUV Colour Lab will also be part of the experience, which is a hands-on colour experimentation station, much like a paint-mixing machine, which empowers colour specialists to formulate with creative flair, giving control back to the stylist and inviting playful exploration. Through these interactive activities, the emphasis shifts away from traditional educator-led sessions and instead encourages discovery through each individual’s unique perception. Chaulk Education further supports this approach by sharing the untold facts often left out by brands and colleges, creating an environment where real knowledge meets real-world creativity.

In an industry where colour education is often filtered through brand messaging, Chalk Education’s is a truly unique approach to colour education.

The tour is set to reach six UK locations throughout 2025, including Guernsey, London, Glasgow, Jersey, Manchester, and Cardiff. For more information or to attend, please visit – Become a Colour Master.
