I have a tree view list having multiples columns of checkboxes. I can change the color of the cell, but I can't change the color of the tick mark or the box surrounding the tick mark only. Any idea?

My code for changing the cell color is:

<field name="unsafe_condition"
       attrs="{'column_invisible': [('parent.scored','!=',False)]}"
       options='{"bg_color": "#FF8080:  unsafe_behavior == True"}' />
