final class Button extends GeneratedMessageV3 with ButtonOrBuilder

A text, icon, or text and icon button that users can click. For an example in
Google Chat apps, see
[Add a
button](https://developers.google.com/workspace/chat/design-interactive-card-dialog#add_a_button).

To make an image a clickable button, specify an
[`Image`][google.apps.card.v1.Image] (not an
[`ImageComponent`][google.apps.card.v1.ImageComponent]) and set an
`onClick` action.

  14. def getColor(): Color

    If set, the button is filled with a solid background color and the font
color changes to maintain contrast with the background color. For example,
setting a blue background likely results in white text.

If unset, the image background is white and the font color is blue.

For red, green, and blue, the value of each field is a `float` number that
you can express in either of two ways: as a number between 0 and 255
divided by 255 (153/255), or as a value between 0 and 1 (0.6). 0 represents
the absence of a color and 1 or 255/255 represent the full presence of that
color on the RGB scale.

Optionally set `alpha`, which sets a level of transparency using this
equation:

```
pixel color = alpha * (this color) + (1.0 - alpha) * (background color)
```

For `alpha`, a value of `1` corresponds with a solid color, and a value of
`0` corresponds with a completely transparent color.

For example, the following color represents a half transparent red:

```
"color": {
   "red": 1,
   "green": 0,
   "blue": 0,
   "alpha": 0.5
}
```


    If set, the button is filled with a solid background color and the font
color changes to maintain contrast with the background color. For example,
setting a blue background likely results in white text.

If unset, the image background is white and the font color is blue.

   "blue": 0,
   "alpha": 0.5

    .google.type.Color color = 3;

    returns
