Never seen that before

I wish I was able to get a pic but couldn't but I was organizing and inspecting my tank when I noticed a frag of my super bright utter chaos frag fell from the frag rack to the sand bed. They awkwardly fell in a tight area so I was able to reach them with a couple fingers. When I grabbed them I noticed a residue was left on my hand and it was the same color as the zoa bright orange. I didn't squeeze them tight enough to injure the zoas but it still left that orange colored residue on my hand. Has anyone ever dealt with that before? What could it be?

Could it just be the detritus behind where it fell? Sometimes our light colors reflect off of it?

its likely to be zoox algae, or rater the dinoflagellate it is expelling that contain the color
