Normally, sedimentary chalk and limestone would be white (or whitish or greyish). The colour of slate can range widely, even creating green, or blue slate. Conglomerate is often coloured by the clay that surrounds the stones embedded in the clay. Even white chalk could appear reddish if contaminated enough by iron sulphates, etc.

Is a sedimentary rock a light color or a dark color?
Sedimentary rocks can vary widely in color, ranging from light to dark shades. Common light-colored sedimentary rocks include limestone and sandstone, which often appear in shades of beige, cream, or light gray. Conversely, darker sedimentary rocks like shale can be found in shades of dark gray, brown, or even black. The color typically depends on the minerals present and the environment of deposition.
Does Light-colored rocks with lower densities form from basaltic magma?
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
Why does rock pocket mouse color influences its overall fitness?
Because of natural selection, most of the light-colored mice live on light rocks, while most dark-colored mice live on dark lava rocks.
Light colored igneous rocks are less what than dark igneous rocks?
Dense. Light colored igneous rocks have lower density compared to dark colored igneous rocks due to their higher silica content, which results in slower cooling and the formation of larger crystals.
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.

How does the density of a light colored rock differ from the density of dark colored rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.

Why do frogs have dark backs in the meadow and light backs around light-colored rocks?
Camouflage!
Do dark rocks absorb more heat than light rocks?
Dark rocks will absorb more radiant heat than light rocks, for the same reason that any dark object absorbs more heat than an equivalent light object. Light objects appear "light" to us because they reflect more light than objects which appear dark. Dark objects appear dark because they absorb more light and reflect less. However, dark objects will radiate more heat that light objects. Actually, dark rocks do NOT absorb more radiant heat than light rocks. Nor do they radiate more heat than light rocks. Dark rocks DO absorb more LIGHT than light rocks and they then radiate this light at heat. Light rocks reflect the light rather than absorb it and therefore do not radiate as much heat. If you put a light rock and a dark rock next to a HEAT source, the amount of heat absorbed will be related to the makeup of the material rather than to the color.
Why are dark colored igneous rocks heavier than light colored ones?
As a first approximation, the colour of igneous rocks gives an estimate of the concentration of iron in it. Very dark igneous rocks commonly a large fraction of minerals with iron as a major constituent. As those minerals are denser than most other silicate minerals occuring in igneous rocks, dark colored igenous rocks are usually denser than the ligher ones.

Why are dark igneous rocks heaver then light igneous rocks?
Dark igneous rocks usually have higher amounts of heavier elements such as iron. Light-colored igneous rocks tend to be richer in lighter elements like sodium and aluminum.
