Select backlight color

For most of the application, the color of the lighting does not matter, especially for opaque parts. For this reason, we advise the standard red color.

It may be difficult to see translucent parts if their color is close to the color of the backlight. The part may merge a bit with the background. This may be the case even with plastic parts that looks opaque to the eye.

In the example below, when illuminated with a red backlight, the contrast between the yellow clips and the background is compromised (even if the clips look opaque with ambient light).

When illuminated with a blue backlight, the same part will have a much higher contrast against the background. This is because the blue color is the complementary color of the yellow and is therefore better absorbed than the red one.

This is because the yellow color is closer to the red than to the blue in the chromatic circle.

To maximize the contrast, the color of the backlight should be at the opposite of the color of the part.
