Color and design influence people in a multitude of unseen ways—shaping our emotions, behaviors, and well-being. In this episode of Colormixology™, host Sue Wadden explores the profound impact of color psychology with world-leading behavioral design consultant Karen Haller and designer Joscelin Mackey, founder of Accessible Design Studios and author of Designing for the Senses.

Karen shares how color goes far beyond aesthetics and is one of the most powerful tools for creating environments that inspire measurable change in the ways people behave. By understanding how color interacts with our brains and emotions, we can design spaces that support well-being, productivity, and even consumer habits. From the high-energy reds of fast-food chains to the soothing tones of a spa, she explains how every color choice sends subconscious signals that influence how we feel and act.

Joscelin expands on this idea through the lens of sensory design and neurodivergence. She discusses how textures, lighting, and color work together to shape our experiences—whether at home or in a beauty-and-wellness space that feels welcoming and warm.

Episode 08: The Psychology of Color & Design

TRANSCRIPT

VO Artist (00:01): Let's see what happens when we dare to color outside the lines. You're listening to Colormixology, the debut podcast from Sherwin-Williams. 

Sue Wadden (00:15): Hello and welcome to Colormixology by Sherwin-Williams, the podcast where we connect with the creative people who are shaping the design and color landscape. I'm your host, Sue Wadden. Last month, we had two experts in AI for design on the show. Jenna Gaidusek of AI for Interiors, and Brandon Dorsey, the technology director at Vocon Architecture and Design. 

(00:36): We went deep into the topic of embracing new technologies and letting creativity be fuel for your strongest AI-generated designs. If you're curious about using AI in your interior design work, definitely check it out. But today, I'm super excited because we're going to get into a different type of design science. 

(00:54): And we'll hear from one designer, who specializes in understanding how color impacts us psychologically, and another who specializes in creating commercial spaces where everyone can thrive. Our first guest is world-leading Behavioral Design Consultant, Karen Haller. Thanks so much for joining us, Karen.
