The figure below demonstrates the combination of light that would be transmitted through a cut-on filter with the stopband and pass­band in the visible range. The red, green and blue curves are color matching functions designed to quantify the way the human eye [perceives color.](https://optics.visimax.com/blog/common-uses-of-optical-filters-an-example-of-led-emission-and-color-perception) When the transmitted spectrum is combined with color matching functions, we can see that the light transmitted through the filter will appear to be orange colored.

In some applications, this full spectrum is acceptable or even desired. In others, however, it may be necessary to limit the wavelengths passing from the light source. This is where [optical filters](https://optics.visimax.com/blog/filtering-light-optical-filters-designed-to-provide-more-desirable-lighting) come in.
