Is there any difference between the colours of PokeBeans?

In Pokemon Refresh and Poke Pelago, you receive and use Pokebeans. These come in a wide variety of colours - with no stated difference between them (except for the clearly-special Rainbow and Crystal beans).

For the standard coloured beans, is there any difference between them? For example, do certain Pokemon like a particular colour's flavour better in Refresh?


Solution 1:

According to Serebii (perhaps one of the most reliable sources on Pokemon information) the color differences are purely aesthetic.
