If a rock has bands of light and dark layers its what?
It could be a sedimentary rock or a foliated metamorphic rock exhibiting alternating bands of light and dark minerals.
Why are fossils sometimes colored?
Fossils are usually found in sedimentary rock. Sedimentary rock derives its color from a variety of sources, but usually from the minerals which compose the rock.

If a rock has bands of light and dark layers it is?
It could be foliated metamorphic rock or sedimentary rock, depending on its mineral makeup and method of formation.

Sandstone is a sedimentary rock regardless of its color.
Why does the color of sedimentary rock change during metamorphism?
The color of sedimentary rock changes during metamorphism due to minerals. New minerals introduced can change the color of the rock.
How do you identify what sort of rock you found?
Of course, since we can't see a picture of your rock, we can't be certain, but here's how you can identify your own rock:What size are the minerals making up the rock?Can't see individual grains and rock is thin and heavy - probably a shale, which is a metamorphic rock made from sandstone that has been squeezed under pressure for millions of yearsCan't see individual grains and rock is brittle and breaks in sheets - probably a sedimentary rock called slate, made of mud packed together over millions of yearsCan't see individual grains and rock looks like a piece of glass - obsidian, which is a volcanic type of glass formed from melting sandCan't see individual grains and rock looks like clay - probably limestone if it's a softer rock or chert if it's a harder rockVery small grains and rock is very hard and usually white or light colored - probably a metamorphic rock called quartziteVery small grains and rock is fairly soft and usually white or light colored - probably a metamorphic rock called marbleVery small grains like sand or mud - an igneous rock called sandstone or siltstoneVery small grains but doesn't look like clay or mud - an igneous or volcanic type of rock called rhyolite (light color) or andesite (medium color) or basalt (dark color)Medium grains - probably an igneous rock called dacite (medium color) or diabase (dark color)Medium grains and looks sort of like concrete with minerals and sandstone pieces in it - a sedimentary rock called graywackeMedium grains with a definite order to the crystals inside the rock - a metamorphic rock called schistMedium grains with definite layers of dark and light minerals - a metamorphic rock called gneissCoarse grains with rounded pieces - a sedimentary rock called a conglomerateCoarse grains with jagged pieces - a sedimentary rock called brecciaCoarse grains with no real order to the minerals in the rock - an igneous rock called granite (light color) or diorite (medium color) or gabbro (dark color) or peridotite (very dark color)Frothy looking with bubbles - an igneous rock called pumice (light color) or scoria (dark color)Made of tiny fossils - a sedimentary rock called coquinaAlternating layers of light colored igneous rock and dark colored gneiss, usually highly folded and contorted - a metamorphic rock called migmatiteOf course, you may have found a piece of a mineral, not a rock at all. Your best bet is to start looking on the internet for photos that look like what you found. Here are a couple of good places to start:Geology.com - photos of different types of rocks with identificationsRock Picture Index - click on the different names to see what the rock looks like
Is color an important characteristic for identifying a sedimentary rock?
i think so because it each sedimentary rock has its own property, and color is an important one
