Hi Anton, 

1️⃣ Why the badge is always grey & how to set colors dynamically

When you use a selection field with the badge widget in a list view, Odoo does not automatically color it based on the selected value.

If no color configuration is provided, the badge defaults to grey.

✅ Correct way to customize badge colors

To control badge colors, Odoo needs an integer field that represents the color index.

Steps (Studio-friendly approach)

1. Selection field

   • Example:

     • Field name: x_status

     • Type: Selection

     • Values:

       • draft

       • confirmed

       • done

2. Integer color field

   • Create another field:

     • Field name: x_status_color

     • Type: Integer

3. List view configuration

   • Add the selection field to the list view

   • Set:

     • Widget → badge (or selection_badge)

     • Color Field → x_status_color

4. Define color values

   • Odoo uses color indexes (same system used everywhere, like CRM stages)

   • Example:

     • Grey → 0

     • Green → 10

     • Blue → 4

     • Red → 1

     • Orange → 3

Example mapping

Automating the color assignment

To avoid manual updates:

• Use Automated Actions (Studio → Automation)

• Trigger: On creation & update

• Condition: based on the selection value

• Action: set x_status_color accordingly

📌 Reference for better understanding: Check the Stage color field in the CRM pipeline — it uses the exact same concept.

2️⃣ Adding a Font Awesome icon inside the badge text

Odoo does not support Font Awesome icons inside selection labels (or badges) by default.

Selection values are treated as plain text, not HTML.

What can be done

• There is no standard widget in Studio to inject Font Awesome icons into a badge

• To achieve this, you would need:

  • A custom widget (JavaScript)

  • Or a custom QWeb view override

This requires development work, not achievable with Studio alone i guess. in case you find any solution let us know 

Possible workaround (limited)

• Use emoji in the selection label (e.g. ✅ ❌ ⚠️)

• Emojis are supported and render correctly in badges
