Your room has completely white walls and a white sectional sofa (60%), neutral floors, upholstered side tables and side chairs (30%), and single-color details in the room with decorative pillows, artwork and other small objects (10%). In reality, the room doesn't have 110%; it's likely that you've removed 10% of the primary or secondary color or a similar combination. If you want to use monochrome colors outside the neutral zone, use a color chart for easy inspiration in your choices. Select the lightest shade of the card (for example, a pale blue) for your 60% main color, use the darkest color (perhaps a navy blue) to guide your selections of 30% secondary colors, and try the central color of the card (a true blue, for example) to give it a 10% accent.
If you want to go for the 110% option, opt for a small dose of a complementary color (in our example, one or two orange accents) to give more life to the monochrome look. It's a classic decorating rule that helps create a color palette for a space. It states that 60% of the room should be a dominant color, 30% should be the secondary color or texture, and the last 10% should be an accent.
