I believe your answer is Paint. Paint is a liquid used commonly on Canvas, but also used on a variety of other things depending on the thickness. If it's thicker, it can sometimes even paint on plaster, which is also common for paint. Paint can be an infinite variety of colors depending on Pigmentation, and oils used. If paint is thinner, it is usually used on Paper. Because it is thin, it will more than likely not bleed through the paper. I hope this helped!
Thanks!

The answer to the question presented above would be 'equal temperament'. The concept of equal temperament divide the octave into 12 tones. This helps avoid the harmonies to be deemed unpleasant when the music is played.
