Barnacles pretending to be nudibranchs?

Description: The picture is of an acorn barnacle (''Megabalanus californicus'') from Santa Barbara, CA. Is it mimicking a nudibranch? The blue and orange tissue resembles a nudibranch in size and shape and it matches the coloration of certain species. Further, when feeding, the barnacle's cirri resemble a dorid's gills. I know this hypothesis is a reach, but why would a barnacle have such conspicuous coloration? I'd like to hear some ideas.
