And this doesn't just happen at congested intersections, it happens everywhere. Now I complain when my brother pulls up practically on the bumper of the car in front at a light, but a couple feet is usually the norm. A car length and a half is STUPID!
Mood necklaces or rings usually contain a chemical that changes color with heat (example cold to warmer black, purple, blue, green, reddish). They then usually have a pamphlet saying what the colors mean.
The moon is always gray. The different atmospheric conditions just make the light appear different colors. The moon is sometimes orange because of refraction. The moon can appear orange when it is low in the sky and when there are a lot of dust particles in the atmosphere. The visible light of the moon is made up of different colors: red, orange, yellow, blue, green and purple (which together appear white).
