The colors in Macedonian....black, white, yellow, blue, green, red, brown, gray, pink, violet and orange....







So,
the color бело (white)
in male genere will be бел
in female gender will be бела
in neutral gender will be бело
in plural (for male, famale and neutral) will be бели

the same is for all the colors

Here are some examples:
Бела кола - White car (The noun 'car' is in female gender in Macedonian, so the color white will be Бела)

Црвен автобус - Red bus
(The noun 'bus' is in male gender in Macedonian, so the color 'red' will be Црвен)

Сиво маче - Grey kitty
(The noun 'kitty' is in neutral gender in Macedonian, so the color 'grey' will be Сиво)

Црни кондури - Black shoes
(The noun shoes is in plural, so the color black will be Црни)


So here is the rule, lets take the color 'blue'
Син - for male gender
Сина - for female gender
Сино - for neutral gender
Сини - for plural

The same goes for all the colors!
