My white arachnoideum seedling and its offspring are currently mostly dark green and red and multiplying happily. I counted more than 50 offspring in total. Now I'm just waiting for the white colouring to return in summer...
As it looks the light yellow centre is returning on this seedling contrasting nicely with the brownish leaves surrounding it. Right is last weekend, left about one week before.
Also its ex-variegated sibling seems to open up and get a lighter centre.
