The AOC Bicolor course (some other Color Bicolor) covers all bicolor kinds that do not match in Blue Green or Red bicolor courses. A bicolor must have a base colour and also the color should go 25 percent of their color. Both colours ought to stand out.
Nothing else 3rd colour that is much more that 15 percent has to be current or it’d took into account a multi-colored Guppy. The dorsal needs to match exactly the colour and pattern at the tail.
