### approximate-rgb

#### approximate-rgb red green blue

Reports a number in the range 0 to 140, not including 140 itself, that represents the given color, specified in the RGB spectrum, in NetLogo's color space.

All three inputs should be in the range 0 to 255.

The color reported may be only an approximation, since the NetLogo color space does not include all possible colors. (See approximate-hsb for a description of what parts of the HSB color space NetLogo colors cover; this is difficult to characterize in RGB terms.)

    show approximate-rgb 0 0 0
    => 0  ;; black
    show approximate-rgb 0 255 255
    => 85.2 ;; cyan
