Hello Omar
You can apply one trick to show different color for selection field.

<field name="gender" string="Gender" style="color: red;" attrs="{'invisible': ['|',('gender','=','female'),('gender', '=', False)]}"/>
<field name="gender" string="Gender" style="color: green;" attrs="{'invisible': ['|',('gender','=','male'),('gender', '=', False)]}"/>
<field name="gender" string="Gender"  attrs="{'invisible': ['|',('gender','=','male'),('gender','=','female')]}"/>

Thanks.

Hello Omar,

Might this work for you

Add decoration in view

This is not working in my case,and also even if it works,then dont you think its not that good an approach because its quite static,hard coded,as you can see that in this example we have just 2 values,suppose when we have more than 2 values,like 10,15 values and I want to give different colors to them

For example the field is country=fields.Selection() and in that field we have 30 countries,so I will have to give different color to all the fields by writing <field='country'.....> 30 times.So is their any better and dynamic solution for this kind of problem like using some widgets or javascript code by which we get the value of selection field when user enters the data like ,document.getElementById('xyz').fontcolor='blue' ,something like this?Any such solution?Does that exist?Suggestion on this problem will be highly appreciated.
