I have a tosai Ochiba which has been normally marked with a golden brown leaf pattern on a pale blue base... until recently. After putting him back in the outdoor pond a strong sumi leaf pattern has asserted itself on his back. If I can get a good picture I'll post it but it isn't easy to get a good shot now that he's back in the pond. BTW, he started out black with a gold outline on the head only and the ochiba pattern rose up from the belly during the first 6 months
My question is simple. Does strong sunlight have this effect on Ochiba's or is he just going kujaku on me???
