How do you change the color of the annotators in Supervision?

FAQ
1

In Supervision, is there a way to configure the color/colors the annotator uses?

Ex: how was this image set to only annotate purple bounding boxes?

You can change the color of most, if not all, Supervision annotators by specifying a color parameter and supplying a supervision.Color or supervision.ColorPalette object.

Create a Color

You can create a Color by using the from_hex method like so:

color = supervision.Color.from_hex("#fff") # For a white hex code

or from a RGB color:

color = supervision.Color(0,0,0) # Equivilant to an RGB code of (0,0,0)

You can also create a ColorPalette using the from_hex method:

color_palette = supervision.ColorPalette.from_hex(["#fff", "#000"])

or you can also create a ColorPalette by supplying a list of Color objects:

# In this example, the supervision name is shortened to `sv` which you can do using `import supervision as sv`
color_palette = sv.ColorPalette([sv.Color(0,0,0), sv.Color(255,255,255)])

Set the Color

For example, in the BoundingBoxAnnotator (as seen in the example image), you can set the color property to purple like we showed previously:

color = supervision.Color.from_hex("#9C66E9")
bounding_box_annotator = supervision.BoundingBoxAnnotator(color=color)
