The Theme tab — color palette and typography on the left, live preview on the right |
Choose your colors
There are five colors you can set. Each has a color swatch (click it to pick visually) and a hex field (type an exact value like #29BBAF).
Color | What it affects |
Primary | Your main brand color — used for prominent elements like buttons and headers. |
Secondary | A supporting color that complements the primary. |
Accent | Highlights — links, the send button, and active states. |
Text color | The color of message text in the chat. |
Background color | The background of the chat window. |
To set a color:
1. Click the swatch and pick a color, or type a hex code (e.g. #0B0B0B) into the field beside it.
2. Watch the Live Widget Preview update.
Tip: Use the same hex values as your website's brand palette for a seamless look. Make sure your Text color has strong contrast against your Background color so messages stay easy to read. |
Choose your fonts
Below the colors, set your typography:
• Font family — pick a typeface from the dropdown (click Select font).
• Base Font size — set the overall text size (click Select size).
Save or reset
• Save Theme (top-right) publishes your palette and fonts to the live widget. It stays disabled until you make a change.
• Reset To Default restores the original Grevon theme — handy if you want to start over.
Important: Saving applies your theme to the live widget on your website immediately. |
