Time to visit your local hardware store for paint samples with varying shades and intensities of colour. Once in hand, enjoy relating the colours to sounds and music. You may find that deep tones refer to a deep purple, uplifting happy songs are an emerald green or turquoise blue. There really is no right or wrong answer here. Let your instincts lead the way!
Artist influences may take on a totally different vision. Take a trip to your local art gallery and see what songs come to mind when viewing the artwork. The texture of a Monet is very different from that of Degas, Picasso or a Renaissance portrait.
Texture is one of the basic elements of music. When you describe the texture of a piece of music, you are describing how much is going on in the music at any given moment. For example, the texture of the music might be thick or thin, or it may have many or few layers. It might be made up of rhythm only, or of a melody line with chordal accompaniment, or many interweaving melodies.
