The 60-30-10 rule is a design principle that is used to create a balanced and harmonious look in a room. It's a great way to figure out which colors to use and where to use them.  The rule goes like this: 60% of the room should be the dominant color, 30% should be the secondary color, and 10% should be the accent color. The dominant color is the color that is used on the largest surfaces in the room, such as the walls, flooring, and larger furniture pieces, it is preferable to a neutral color. The secondary color is used on smaller surfaces in the room, such as the furniture and accessories. This color should complement the dominant color and add some visual interest to the space. The accent color is used in small doses to add a pop of color and create a focal point in the room. This is where you can use a bolder color or pattern to create an accent wall. At last, it's all about creating a harmonious balance of color and texture in the space. The 60-30-10 rule is a great way to help you keep the design principles in mind.
