Exhibiton- Brand name ideas

I have decided to rebrand the name of our company and have come up with some new ideas as to what we should be called. I was thinking along the lines of Paper and ink, as this is what our original name was and have came up with PULP RAINBOW. Pulp- because of paper, and rainbow because of ink/colour wheel/colour spectrum. Here are some of my ideas for fonts and designs. 

I think that if we were to have a logo, it would be a simple colourful shape, like a ball of paper with maybe drips of colour running through it or even the CYMK colours dripping through it instead.
