Why âgreen lightsâ work to attract fleas Fleas eyes are especially sensitive to the colors yellow and green as these are the primary colors of vegetation.

Why fireflies light up And maybe you’ve wondered – how and why are these insects able to light up? The answer is that fireflies contain an organic compound in their abdomens called luciferin. As air rushes into the abdomen, it reacts with the luciferin. A chemical reaction gives off the familiar glow of a firefly. This light is sometimes called “cold light” because it generates so little heat.

- (Detectors like this are called colorimetric because they detect and measure a color change in the chemical blob.). Photo: How an electronic, colorimetric carbon monoxide detector works. An LED shines through a colored chemical detector onto a photocell. When carbon monoxide is present, the detector changes color, the beam is interrupted, and the photocell no longer picks up light.

- This means that a yellow object will appear red under red light, and green under green light. Yellow does not contain blue, so it will appear black under blue light. White objects reflect all light, so will appear to be the colour of the light on them. Black objects, conversely, absorb all the light, and do not reflect any, so always appear black. Most white light also contains infra-red, which we cannot see. Infra-red is heat energy.

So a yellow object under white light will absorb most of the colours of light, and reflect back the yellow light, so we can see yellow. Because yellow light is a mixture of red and green light, yellow will also reflect red and green light.
