It is possible to customize the logo displayed to the end user, as shown in the image below:

To request the inclusion of this logo, you need to send the Unico team an image in .PNG format, with a size of 56x56px.

{% hint style="warning" %}
Rules:

* Prioritize the application of the logo on backgrounds that guarantee legibility.
* Do not use logos that do not respect the square grid.
* Avoid using low-resolution logos.
* Do not apply the logo on transparent backgrounds.
  {% endhint %}

{% hint style="success" %}
**Recommendations:**

* Prioritize colors with a readable contrast of at least `4.5:1`, following [<mark style="color:blue;">WCAG</mark>](https://accessibleweb.com/color-contrast-checker/) accessibility parameters.
  * Use the hexadecimal of the colors to check the contrast scale. Example: *Foreground ColorPicker:* `#000000`, *Background Color:* `#FFFFFF`, *Contrast Ratio:* `21.00:1.`

## Customizing the color and shape of buttons

Throughout the implementation process, it is possible to request the configuration of the color and shape of the buttons in the IDPay interface, according to the company’s visual identity, as shown in the images below:

{% hint style="success" %}
**Recommendations:**

* **Choose accessible colors:** When customizing button colors in By Unico, opt for an accessible color scheme that ensures visibility for all users, including those with visual impairments.
* **Contrast ratios:** Aim for a contrast ratio higher than `4.51:1` for the best results.

Accessible colors improve navigation for everyone, especially for people with low vision. Use hexadecimal color codes to check contrast and follow [<mark style="color:blue;">WCAG</mark>](https://accessibleweb.com/color-contrast-checker/) guidelines.

* **Example:** `#FFFFFF` (text) on `#000000` (background) results in a contrast ratio of `21.00:1`.

### Rounding the button corners

In addition to text and background colors, you can also define the button's corner rounding (border-radius) in pixels, according to the scale below:

### Customization settings

To configure the visual identity of the client or partner for the button, share the following information with Unico's implementation team:

* Hexadecimal color code for the button's background.
  * Example: `#000000.`
* Hexadecimal color code for the button’s text.
  * Example: `#ffffff.`
* Button corner rounding in pixels.
  * Example: `10px.`
