The plugin supports colors from the Jenkins palette colors. For example, the following are all valid references to the Jenkins palette colors:
addBadge icon: 'symbol-star plugin-ionicons-api', text: 'A star', color: 'yellow'
addBadge icon: 'symbol-star plugin-ionicons-api', text: 'A star', color: 'dark-yellow'
addBadge icon: 'symbol-star plugin-ionicons-api', text: 'A star', color: 'jenkins-!-color-yellow'
The plugin supports colors from the Jenkins semantic colors. For example, the following are all valid references to the Jenkins semantic colors:
addBadge(icon: 'symbol-star plugin-ionicons-api', text: 'A star', color: 'warning')
addBadge(icon: 'symbol-star plugin-ionicons-api', text: 'A star', color: 'success')
The plugin also supports CSS colors for icons not from the Jenkins symbol library. For example, the following are all valid references to CSS colors:
addBadge icon: '/path/to/icon.svg', text: 'A star', color: '#7fffd4'
addBadge icon: '/path/to/icon.svg', text: 'A star', color: 'rgb(0, 0, 256)'
