Yes Susanne
The color is YELLOW! and thare is as the surface is covered by a fine layer of yellow frost that glisten in the right light. (This effect is not so apperant in the picture)
The flower is 4.5*4.5 cm (1.5''*1.5'' ?)
The pot is 10 cm (3''?)
I grow it in pure gravel/stone with a few pieces of pine bark. It should dry very fast after watering and it should have a cooler winter rest with very bright light. Atleast what I have read.
