It is best determined by radiometric dating techniques which measure the decay of radioactive elements.
Relative age can be determined using superposition and cross-cutting relationships. Absolute age can only be determined using radiometric dating methods, such as Rb-Sr.
The color of an igneous rock is mainly determined by the minerals present in the rock. Different minerals exhibit different colors, such as feldspar being pink or white, while olivine is green. Additionally, the texture and size of mineral grains can also affect the overall color of the rock.

The absolute age of an igneous rock can best be determined by radiometric dating methods, such as uranium-lead dating or potassium-argon dating. These methods rely on the natural decay of radioactive isotopes in the rock to calculate the time elapsed since the rock formed.
An igneous rock's color is mainly determined by its silica content.

When magma crystallizes, it becomes igneous rock. Igneous rocks are formed by the cooling and solidification of molten rock material. The texture and composition of the igneous rock are determined by the rate of cooling and the mineral content of the magma.

Extrusive igneous rocks. The type of extrusive igneous rock is determined by the composition of the lava.
igneous
You could determine whether the rock cooled underground or above the surface.
If igneous or metamorphic ( though metamorphic rock is hard to do ) radiometric dating can be used. The radioactive substance that may be in igneous rock devolves into a daughter substance and the rate of this change, coupled with other parent/daughter changes, give one a very precise age on the rock being examined.Google radiometric dating.
