The bottom star is layered bottom red pv19 and tit white and slight yellow, and on top, pv23 and ult blue and tit white aand pthalo green slight... it creates a good contrast without being gaudy because of the white similarity and the pv19 and yellow underneath-I did not wait for it to dry.

the blue/green at top is useless but the star at top works. It is heavily muted with white and contrasted by the surrounded colors but still similar through muted white.

yellow and the red below in a long line do nothing. and are worthless

white over Green over yellow, more, did nothing...

on bottom, pv23 and white vibrates with star, see star colors and vibrates by hue similarities
