    I would only do that if I weighed the dyes on a milligram scale which is what I do. It only takes a very small of red to change yellow. I use a micro scoop spatula and a weigh boat.

    To dye 10 grams of material yellow I use .2 grams of dye. For sunburst, I would use something like .02 grams of red.

    That is what I use as well. So, the question remains. Large amount of yellow, weighed precisely. Very small amount of red, weighed precisely.

    1) Add them together.

    2) Add the yellow and allow it to strike. Then add the red.

    What difference would there be, if any?

    The difference isn't chemical. It's according to what your eye sees. Art rather than science.

    If 1 and 2 above produce results that the eye can see a difference in, then the reason for it must be scientific, surely?

    And the question is still the same. Will the eye see a difference between 1 and 2 above?

    If the amount of dye is the same then the end result will be the same. My point is for someone mixing by eye (art) rather than by weight (science).

    Thanks - that is an answer to my question. However, there is some evidence to suggest it may not be the case with dyes of different molecular size. See upthread... Post #17.

    Sure, I think we are already agreed on that. See upthread... Post #15 in particular.

    For those among us, that use micro-scales. You might find that the dye powder can not only erode the weighing area, but also the dye can get into the smallest gaps, like those around the same area. To prevent this, just use a new small waxed paper cake cup, for each colour/batch.

    ... or if you can get hold of a supply of laboratory 'weighing boats'...
