I'm not a Jackson expert, but there not known for there extravigant color changes.. that's more a panther veiled quality. Jacksons are Awsome cause of there horns
Yea he will have his darker light absorbing/stress colors and his bright fired up sleeping light reflecting colors. But far as i know he's not gonna spit any yellow blue or reds out at u... Ever
Baby Jacksons show red in the gular region when extended. Monty showed his quite a bit when I first got him. Now he's 8 months old, he's varying shades of green with almost yellow patches along his side. As already said, Jackson's charm is with the horns rather than colour. Panthers and Carpets are the more colourful species. I love Monty's 'face furniture' and his wonderful teal green patch under his chin! They are beautiful in a different way.
