TC Arctic Halo hub A rainbow of color packed

A rainbow of color packed onto stocky branches: a lemon yellow-green body

with corallites rimmed in neon yellow and set with cool blue-lit mouths

and under actinic light the whole colony reads saturated purple with electric tips

Packed corallites make the pattern here: lime-green to chartreuse walls ringing centers that glow purple and blue

The lime tips brighten toward the ends while the branch bases stay teal

TC Arctic Halo hub A rainbow of color packedIcy white to frost blue axial tips crown each upright branch, glowing like a halo above a teal to blue green base. Dense, fuzzy polyp extension gives the branches a plush, snow dusted look, and neon green flecks light up at the corallite mouths. The cool tones hold under blue spectrum lighting.
