Sky blue: rayleigh scattering is why the sky is blue, red and orange wavelengths are not reflected like the blue ones near the sun clouds hce dark centers and light edges , the color of sky is duller (wamrer mixes with blue) looking away from the sun, sky is bluer and more vibrant towards violet near the horizon blue sky is lighter (looking through more atmosphere) atmospheric perspective, things in foreground if far enough in the distnce can change to match the color of the sky white doesnt act s dark objects, gets warmer (ie sunsets) reverse tmospheric perspective happens in areas like sunsets, everything gets warmer going backwards because this is uncommon it cn be used to create feeling of strangeness or excitement Snow and clouds are different, snow is much denser and picks up reflected light Water is reflective at an angle and less so when looked at the surface straight on Wats filters out certain wave lengths first red then orange yellow leaving blue cast
