Perhaps "rainbow" is the name of the company. I own all three known types of jacksons chameleon and have attached pictures below. In my (biased) opinion, they are all beautiful with their mix of greens, yellows and blues. (Please excuse the quality of these pics as they were all taken by my phone....but you get the idea.)
View attachment 159707 Above is the most common and least expensive of the jacksons chameleons, jacksons xantholophus. It also tends to be the largest of the three. If you buy a "xanth" it will probably be CB (captive born) or WC (wild caught) from Hawaii. Males have three horns and females usually have none.
View attachment 159708 Above is a much less common jacksonii jacksonii. If you buy one of these, it will most likely be WC from Kenya (or CB in Kenya and then shipped to the US). This is a male. Males have three horns and so do females. A female pic is below. Immediately below are several close up images of my male's colorful scales. Jacksonii jacksonii (jj) are about $150-200 plus shipping.

View attachment 159710 View attachment 159711 Above is a female jacksonii jacksonii. Notice her three horns. Below is a close up of my male's shoulder.
View attachment 159713Below are pictures of three different male Mt. Meru Dwarf Jacksons, members of my cham fam. These are a bit smaller than the other two species of Jacksons. They are my favorite. Males have three horns and females have one on the tip of their noses (and are super cute). They have varying amounts of yellow on their heads and often have blue/turquoise coloring on their flanks. Females tend to be more green &/or brown. If you buy one of these, it will cost about the same as a jacksonii jacksonii and be about as hard to locate. If you purchase it from a large, well known reptile breeder will probably be WC from Tanzania. If you buy it from a private individual, such as someone here on Chameleon Forums, it will most likely be CB.

All three jacksons species are montane species and have almost identical care though Mt. Meru require smaller enclosures and generally eat less due to their smaller size. All are equally enjoyable. JACKSONS RULE.....BECAUSE THEY'RE SO COOL!!!!
