Acrylic colours are available in solid or opaque, translucent and transparent options. While no or minimal light will pass through an opaque colour, light passes through a transparent colour undistorted, enabling us to clearly distinguish objects.
In contrast, translucent colours are partially transparent permitting the passage of light without enabling us to distinguish the colour of objects seen through them.
