Blood?
I'm red, but I can also be blue
humans have red blood, but nobles were sometimes referred to as having blue blood because they never went outside
When in a lizard, I might be green
I'm thicker than water, and I have a slightly higher density.
"Blood is thicker than water"
I have to do something with a monkey, but the connection might be negative
Rhesus factor (Thanks, @RadoslavHristov!)
I symbolize both life and death
You need blood to live, but bloody is often negative and connected with death

3$\begingroup$ The monkey link is the rhesus factor. Also insects have no blood so I guess we have a reference to royal, i.e. "blue" blood. $\endgroup$ Jul 26, 2016 at 9:36

2$\begingroup$ This was the intended answer. Indeed, blue is a reference to royal. Also, Cephalopods (inkfish) in fact have blue blood. $\endgroup$ Jul 26, 2016 at 9:46

$\begingroup$ If it's not obvious, the "might be negative" part refers to the Rh factor in the blood type, which can be positive or negative like o-positive or ab-negative, for example. $\endgroup$– EyalJul 26, 2016 at 10:47
