The deal here is Do It (as with most others too) buy the pigments and dyes from a manufacturer and cut them so they can be bottled and sold. So what they may mix and bottle and call non bleed may actually have components that will bleed to varying degrees. The reason I had made the switch to mainly using Spike It's colourants is because they are the manufacturer. They have always labeled their colourants to differentiate bleeding and non-bleed colours (this new rating on the website takes it a step further). Also, if I need a specific colour mixed they can and will get it done, look at their Mint Brown, I had them duplicate Bear's old Chocolate Mint colour that was no longer made.
