Question

what can i do to make my vegatarian uromastyx lizard more colourful. like feedin her something to intensify its colour?

Answer 1

The lizards' color changes according to the temperature, during cool weather they appear dull and dark but the colors become lighter in warm weather.

You can't do anything to change their colors.

The coloration of this lizard has a great deal of variety and is therefore
very difficult to generalise. The colour of any U.acanthinurus may differ
depending on a number of factors such as: -

Age, Temperature, The amount of Ultra Violet light available and even mood.

A healthy, warm specimen usually has bright pastel colours such as yellow,
orange and green. A common adult pattern is black legs and head while the body
remains bright with one of the above colour's mentioned. The lizards also
sometimes have patterns such as stripes (bars across the back) and spots. The
pattern and colours are always over the back, while the underside remains
quite dull. Males are brighter than the females and often show red heads when
ready to breed.

Very young Spiny-Tails do not have bright colours and tend to just be a kind
of light brown colour, as they get older they will develop dark mesh work
across the back and quite often will have darks markings around the eye
connecting to the jaw. I think that the most appealing feature to me must be
the very strong eyebrows and short snout that make the North African Spiny-
Tail look very majestic in nature.

Answer 2

Theoretically more beta carotene would help, but I'm not sure...

Uromastyx get brighter as they get older, and the males generally have more intense coloration than the females... There's only so much you can do. Coloration also greatly depends on species (Egyptians are drab, Malis are yellow/black, Saharan/Nigerians are yellow red or orange, ornates can be brilliant blues and greens etc...)

The best advice would be to invest in a mercury vapor bulb, which has a much stronger UV output than fluorescents... Increasing UV is generally a reliable method for intensifying color (as well as increasing feeding response and natural behavior, etc...). Megarays are the best, but are also very expensive ($75-85)

Answer 3

Ultraviolet light and vitamin D supplement on it's veggies and fruit should do the trick.
