Unless you need a thick blank for segmenting or laser cut pieces, I've found it easier to turn the blank to finished size, then dye the surface to the colors wanted, and seal under CA. It's quicker, uses less dye and you have more control over the finished color. I've used a few different dyes liquid and powder with good results. I always mix the powder with denatured alcohol. Avoid water based dyes or you'll wait forever for the wood to dry afterwards, and risk messing up your ca finish. Gluboost Master Tints also work well for coloring wood.
