Select element does not honor admin color scheme on hover

[vaakash]

When select elements are hovered, the text color changes to the "default color scheme" and not to the color scheme selected bu the user.

For example, the user has selected "sunrise" color scheme the hover color on the select element should be from the "red/orange" palette. But it has the default color scheme's blue color.

Since all other inputs honor the color scheme color select element should also follow the same.

The fix should be that below selector should be added in color scheme CSS files with the respective scheme color.

.wp-core-ui select:hover {
    color: #007cba;
}
