Q: How to change color in Tree View odoo using two function I would like to know how to change the color of line in Tree View using two function.
I already using like this :
<tree string="Keep Lines" colors="red:is_move==False">

I want to include two function on there like :
is_move==False and is_expired==True
How to include that? Thanks

A: I see, just add "and" on there, it will be like :
<tree string="Keep Lines" colors="red:is_move==False and is_expired==True">


A: This will work, try this:
<tree string="Keep Lines" colors="red:is_move==False;is_expired==True">

In .xml 
<, >, <=, >= is not supported. 
So we need to use &lt;, &gt;, &lt;=, and &gt;=.
