How many paint colors should a house have?

There is no rule. Many cohesive homes use one main neutral, one or two related neutrals, one white and a couple of accents.

Do all rooms need the same color?

No. Rooms that are visible from each other should coordinate, ideally through a shared undertone and related lightness.

What is an analogous color scheme?

Colors next to each other on the color wheel, such as blue, blue-green and green.

How to pick coordinating paint colors

Short answer: Build your palette around a few fixed elements and one consistent undertone, then vary lightness for flow: a main wall neutral, a lighter and a darker partner, a trim white and one or two accents. Colors that share an undertone coordinate easily. Classic schemes like monochromatic, analogous and complementary give you a reliable structure.

A simple palette structure

Main neutral: the color for open, connected spaces.
Lighter partner: for halls or dim rooms.
Deeper partner: for a den, office or cabinetry.
One white for trim and ceilings (see choosing white).
One or two accents for doors, a bedroom or a powder room.

Color schemes that work

Scheme	What it is	Feel
Monochromatic	Tints, tones and shades of one hue	Calm, cohesive
Analogous	Neighbors on the color wheel	Harmonious, natural
Complementary	Opposites on the wheel	Lively; use one as the accent

Keep undertones consistent

The fastest way to clash is mixing warm and cool neutrals in rooms that see each other. Read warm vs cool undertones.

Check sightlines

Stand where you can see several rooms at once and hold samples together. Colors visible from one spot should look like a family. Test them together under the same light: how to test.

Test it on your wall first

Peel-and-stick samples are made with real paint and move from wall to wall without brushes or patches.
