What are paint undertones and why do they matter?
What Undertones Are
Every paint color has a base hue (what you see first) and undertones (the underlying colors that modify it). For example, a gray paint might have blue, green, or purple undertones.
Undertones are created by the mixture of pigments. They can be warm (red, yellow, orange) or cool (blue, green, purple), or neutral.
Even a tiny amount of undertone can dramatically change how a color reads on your walls.
Why They Matter
Undertones influence how a color interacts with your lighting, furnishings, and fixed elements. A gray with blue undertones can feel cool and crisp, while one with green undertones might feel softer and earthier.
They also affect how colors coordinate. If your flooring has warm undertones, a cool-toned wall color might clash.
Understanding undertones helps you predict whether a color will look as expected in your home.
- Undertones are the subtle secondary colors in a paint.
- They can be warm, cool, or neutral.
- They change how a color looks with your lighting and decor.
- They help you coordinate paint with flooring, cabinets, and furniture.
Common mistakes
- Thinking that a color name (like 'greige') tells you everything—undertones vary by brand and formula.
- Ignoring undertones when matching paint to existing finishes, leading to clashes.
- Assuming a color will look the same in your home as it did in the store or online.
