[Error]Can't find the right color number for black

I have tried many different numbers in

paintutils.drawPixel( x , y , --[[This is the number i need]] )

However I can not find black, so this dude that commented after original post said to do something with

colors.black()

and i tried

local id, black = colors.black()
paintutils.drawPixel( x , y, black )

And i get an error saying "Attempt to call number"
I would like help in this.

Just use the "color" API. In a computer type "help color".

I get something that says attempt to call number, i forgot to mintion its a paintutils.drawPixel( 25,12,–[needs to be black-])

i found out what i did, if a mod could please close this, that would be awesome
