Cosmetics Formulation Development

Hello, I would like to ask if the color used to decorate the color of the serum. (Just need a color to cover the color of the extract that is put into the serum. I don't want it to be applied and the color sticks to the skin) and doesn't dissolve in water. (I made a serum beads and gel นำพา that supports the beads, want it to be transparent and not seep out of the beads) Can you recommend a color please? used The color of the extract is quite dark. and then soluble Enough is mixed in the beads. Then put the beads into the clear gel. Found that the color of the extract, it came off from the beads, absorbed into the clear gel, making the product look unappealing. Do you have any advice for this point, thank you very much.
