Explanation
Most adjectives have four forms: alto, alta, alti, alte. A second group ends in -e and has only two: grande (singular) / grandi (plural), used for both genders. Unlike English, the adjective usually follows the noun (una casa grande), though a few common ones normally come before (bello, buono, grande, piccolo, giovane) and can shift meaning by position: un grand'uomo 'a great man' vs un uomo grande 'a big man'. When one adjective describes both a masculine and a feminine noun, the masculine plural wins: Marco e Anna sono simpatici.
Examples
Note
Colours from nouns never change: una giacca blu, due giacche blu (also rosa, viola, marrone in careful use).
