Question

An antibaryon has three antiquarks with colors\[{\rm{\bar R\bar G\bar B}}\]. What is its color?

Short answer

The color of an antibaryon which has three antiquarks with colors \[\overline R \,\overline G \,\overline B \] is white.

Step-by-step solution

Concept

\[\overline R \,\overline G \,\overline B \]are known as secondary visible colors, and when a color combines with an anti-color or when these three color combine, they produce white color that cannot be distinguished.

Find the color of an antibaryon

\[\overline {\rm{R}} {\rm{ = }}\]cyan = white - red

\[\overline {\rm{G}} {\rm{ = }}\]magenta = white - green

\[\overline {\rm{B}} \]= yellow = white - blue

\[\overline {\rm{R}} {\rm{ + }}\overline {\rm{G}} {\rm{ + }}\overline {\rm{B}} {\rm{ = }}\]white - red + white - green + white - blue

= White

Therefore, it is white.
