I prefer coloured tubing tbh. You gotta remember that the more you add to plain water (dye, coolant etc) the less cooling properties it will have and there is also the chance of dyes clogging the extremely fine nozzles in some cpu blocks.
Dyes will also go 'off' after a time so are also a pita to maintain (regular changes to keep the colour looking bright). Clear tubing will also cloud after a while so that will also need replacing as it looks unsightly.
