# Changing Spline Display Properties

You can change spline display properties in the Display tab. For example, you can change the colour of tangents on the splines you draw. This is useful to better contrast the spline’s tangents from the clip so that they are easier to work with.

Normals button
  Enable to display normals along the 3D path.

Normals colour pot
