Answer is: OsO₄ (osmium tetroxide or osmium(VIII) oxide).

Osmium(VIII) is colourless, but most samples appear yellow, because of the presence of the impurity OsO₂ (osmium(IV) oxide), which is yellow-brown in colour.

Cr₂O₃ (chromium(III) oxide) is light to dark green compound. It is used as a pigment. In this chemical compound chromium has oxidation number +3.
