Danger can result in bleeding, and blood is red in color. Yellow has no such associations; it is associated with sunshine and buttercups.
Technically, it's possible. In the dark, color actually DOESN't exist! It's not that you can't see it, it's just GONE. If you had infrared goggles, everything would be an eerie weird color. That's what happens when you get a wavelength longer than red, but still visible. Color is just what happens when a particular object absorbs all of the colors but one. If there is a red stop sign, the stop sign is reflecting only red, after a prism in the pigments of the paint used to pain the sign breaks the light wave into a spectrum. To answer your question, It's very likely and highly possible that atoms could have color if we could observe them. But here's one thing for sure. it's NOT THE ATOMS THAT MAKE THE COLOR! just because a pencil is yellow, doesn't mean the atoms of the paint are yellow. It means that there are atoms that form to make something called a pigment, which breaks the light wave into the spectrum, and reflects the one color that you see (yellow).
Visible light ranges from longer red light wave to shoter violet light waves in the spectrum,so the red stop sign light waves are longer.
The wavelength of an X-ray is much shorter than the wavelength of a red light from a neon sign. The frequency is much longer in an X-ray than the frequency of a red light from a neon sign.
They change colors to show you what to do on the street. Green means go and that everything is O.K., Yellow means slow down and warns you that you will have to stop soon, red means stop and that it is not safe to keep going, flashing yellow lights are ment to tell you to slow down and be careful, and red flashing lights are meant to be used as a stop sign were you have to wait for others to pass to be able to get through it's also a warning sign for high traffic.
After stopping, you may turn right, unless prohibited by some other sign or signal.
The color sign of the Blue, Red, Yellow is usually represented by RYB.
1) Yellow flashing light of a stop light. 2) when the yellow light for a "school zone" is flashing.the yield sign, the school crossing sign, and the yellow light are all signs of you must slow down.

red is a sign for danger
Yellow light symbole
Not really, I usually ge it in the morning, or when I haven't eaten anything yet.
A black and yellow striped road sign alerts you to a hazard. It means that there is a danger close to the road up ahead. You should be careful and alert when proceeding.
yellow with black letters
They can be white, green, yellow, red, or a combination of these colors.
a little yellow light that blinks.
When a light is not being controlled (it might be broken or nighttime), one direction flashes yellow while the other flashes red. The yellow light should be interpreted as a yield sign and the red light should be interpreted as a stop sign.
