As Matrix says, it will work fine. The colour charging 'effect' is so subtle as to be largely insignificant. The different coloured waxes are really grouping different raw ingredients together (dark beeswax, black montan wax in the dark coloured waxes... coconut oil, white beeswax in the light ones... we wanted people to have a choice of ingredient bases and it made sense for the dark ingredients to suit dark paints).
The funny thing is that we have never oversold their characteristics (as in claiming that they substantially alter the colour of paint) just that the products will suit certain colour hues. People seem to make more of an assumption that they do and I spend a bit of time advising people that it doesn't make a whole lot of difference. See the post here:

You'll find that some recipes are fractionally different performers regardless of the colour (Dave KG is a big Banana Armour fan, for example) and that any wax can go on any colour car if you wish - sometimes people claim a good effect by using a dark colour on silver for example, but I am not sure how much is psychological. The wax layer will be a coloured coating but it is too thin to make a large or noticeable difference, although mutliple layering of contrasting colours does show it isn't an absolute myth (see the thread above).
