Trisense uses the Material icons set by Google. You can adjust the icon colour, alignment and size.
Here are a list of all the available material icons.
Icons can be given any color value. This could be a hex color value or rgba color value.
[icon icon="favorite" color="#bbb"]
Icons can be left (default), center or right aligned.
[icon icon="favorite" align="center"]
Icon sizing comes in 5 different sizes: sm (Small), md (Medium – default), lg (Large), xl (Extra Large) and xxl (Extra Extra large)
[icon icon="favorite" size="sm"]
If you have your own set of SVG icons, you can put them in the Trisense themes image folder and use these icons. More details in the docs.
