colour in relation to sound

 I want to include colour relating to sound and I will do my best to include it I found these images that I think helps show how the two relate

This picture shows how colours grows from blueish to a pinkish colour kinda like a rainbow

This Picture shows the relation between sound and colour,   the lighter colours are linked to quieter noises, the darker the colour is the louder the noise is....

I think that if colour is included, which I will do my best to include, it will get darker if the sound is lower and will get lighter if the sound is higher.....

I think that the best way to include colour is moving from light yellow to dark red, the lighter yellow being the higher sound and the darker red being the lower sound.....

I want to include this because I think these colours relate the most to the sound scales and it also links back to my original idea of including stars, kind of like the different stages of a stars cycle....
