Alkali metals are not colored. Some elements which are colored are in the d-block of the periodic table (transition metals) like Cu, Ag, Au etc,.
Well alkali metals may be white or silvery, so they are generally considered colorless.

Alkali metals are black or silver, because they absorb most of the visible light spectrum.
When you encounter these in a lab, they probably are not a shiny silver color. This is because they have a coating of the metal oxide on the surface.

Alkali metals are silvery grey, but quickly corrode over when exposed to air. They are kept under oil.

Unless white is a colour, alkali metals are colourless!

as far as I know alkali metals aren't colored when they are at their normal form. However, when they burn, they will have different colors. For example natrium burns with yellow flame, potassium with purple one and Lithium with blue one, and we call that spectrum. Believe me because I've seen those before in the lab

They are like typical metals in that they are a silvery color in their native form. They do oxidize quite quickly in air, however, their oxides are still not colorless.
