Final answer:
The color of an antibaryon with the anticolors ¯fer¯G¯B is color neutral or 'white', as it includes all three anticolors corresponding to antired, antigreen, and antiblue.
Step-by-step explanation:
An antibaryon is composed of three antiquarks which are analogous to the three primary colors in visible light, except in the realm of particle physics, these colors refer to a quantum number rather than actual color. An antibaryon has the anticolors cyan (¯fer), magenta (¯G), and yellow (¯B) which correspond to antired, antigreen, and antiblue, respectively. When these anticolors combine, they produce color neutral or 'white', just as combining red, green, and blue in the visible spectrum produces white light. Therefore, referring to Figure 33.19, the combined color of an antibaryon with anticolors ¯fer¯G¯B is white, which is necessary for color neutrality in hadronic particles.
