Browse by Light & Depth
A color's LRV (Light Reflectance Value) decides how light or heavy it feels on the wall. Browse from the brightest whites down to the darkest near-blacks.
Lightest & Most Reflective
The highest-LRV shades — the brightest, most reflective colors here, the ones that open up dim rooms and lift low ceilings.
Versatile Mid-Tones
Balanced colors around 50 LRV — enough depth to read as a true color without darkening the room.
Darkest & Deepest
The lowest-LRV shades — the deepest, most dramatic colors here, for accent walls, doors and moody, cocooning spaces.
Warm vs Cool Colors
Color temperature changes how a room feels and reads. Warm tones cozy up a space and counter cold light; cool tones calm it down and make small rooms feel larger.
Warm Colors
Reds, oranges, yellows and warm earth tones — they advance toward you, making large rooms feel cozier and north-facing rooms feel sunnier.
Cool Colors
Blues, greens and purples — they recede, making small rooms feel larger and hot, south-facing rooms feel calmer and more spacious.

How to Choose a Paint Color
Choosing interior paint comes down to three things: light, LRV and undertone. The same color looks warmer in a south-facing room and cooler in a north-facing one, so always judge a paint in the actual space rather than from a chip in the store.
LRV (Light Reflectance Value, 0–100) tells you how light or heavy a color will feel — high-LRV whites and neutrals brighten dim rooms, low-LRV colors add depth and drama. Every color page in this catalogue shows its exact LRV and undertone.
Undertones are the hidden hues beneath the surface — a gray that leans blue, a white that leans cream. They decide whether a color harmonizes with your floors, counters and trim, so check them and test two or three samples on the wall in both daylight and night light.
Color Theory Basics
Four schemes that make a palette work. Use them to pair a wall color with trim, accents and furnishings.
Complementary
Opposite hues on the color wheel (blue + orange). High contrast and energy — use one as the dominant color and the other as a small accent.
Analogous
Three neighbors on the wheel (blue, blue-green, green). Calm and harmonious — the easiest scheme to get right in a home.
Monochromatic
One hue in several values and tints (pale to deep blue). Serene and sophisticated, with depth coming from light and shadow.
Triadic
Three evenly spaced hues. Vibrant and balanced — keep one dominant and the other two as accents to avoid chaos.
Paint Sheen Guide
The same color in a different finish behaves differently. Match the sheen to the surface and traffic.
Our color tools run on our own catalogue of 26,000+ real paint colors across 16 brands — Benjamin Moore, Sherwin-Williams, Behr, Dulux, RAL and more — with the color math (HSL and CIELAB matching) computed in-house, not scraped from summaries. Every color you pick maps to a real, buyable paint with its code, so what you see here you can actually take to the store. We review and update these tools and their data regularly.

Frequently Asked Questions
How do I choose the right paint color for a room?
Start with the room's light and purpose: north-facing rooms suit warmer tones, south-facing rooms can take cooler ones. Pick a family, then narrow by LRV and undertone. Always test 2–3 samples on the actual wall in daylight and at night before committing.
What is LRV and why does it matter?
LRV (Light Reflectance Value) measures how much light a color reflects, from 0 (black) to 100 (white). High-LRV colors brighten dim rooms, low-LRV colors add drama and depth. Every color page here shows its LRV.
How do undertones affect a paint color?
Undertones are the subtle hues beneath the main color — a gray can lean blue, green or purple. They're what makes a color clash or harmonize with floors, counters and fixtures, so check undertones before buying.
How many paint samples should I test?
Test two to three finalists at once. Paint large swatches on more than one wall and look at them in morning, afternoon and evening light — color shifts dramatically with light, so never decide from the chip alone.
What paint sheen should I use in each room?
Use flat or matte on ceilings and low-traffic walls, eggshell or satin in living rooms and bedrooms, and semi-gloss on trim, doors, kitchens and bathrooms where you need washability.
Can I match a paint color to another brand?
Yes — every color page here shows the closest match in all 16 brands (Benjamin Moore, Sherwin-Williams, Behr, Valspar, Dulux and more) with each brand's code and a ΔE closeness value, so you can buy the same shade wherever you shop.
