Picking a colour scheme is something you will probably work to try and create, but you might not even be aware that you’re doing it! This is usually where people tend to over-complicate things for themselves and get confused because they start to worry about which colour will look good with what and if they can actually make it work in their space.
As a general rule of thumb from the professionals that always works when you’re working to create your own colour scheme, if you’re splitting up your space by percentage — paint 80% a neutral colour (the most popular being gray or taupe-beige). Have 15% as a shade neutral colour — so, if you picked gray, a lighter gray. And have 5% of the space be an accent colour that nicely complements things. This train of thought when it comes to picking out paint colours works practically every time.
Of course, you can absolutely go by your own personal preference and design aesthetic when it comes to choosing paint colours, but there is such a thing as harmonic colour schemes, which can help along the way. Harmonic colour schemes consist of two or more colours on the colour wheel which have a specific relationship based on their position and distance from one another. They tend to work together nicely in perfect harmony.
