Learn how to pick your colors

If you are unsure about how to play with the colors of your interior, I would recommend you to start with a monochromatic scheme with different "Saturation values", or with a "Complimentary scheme". If you know a bit more about color, go for an "Analogous scheme". I would recommend you to stay away of the "Triadic scheme" as you need a bit more training on understanding how to make it work with "saturation" and "value".
