The whole masculine - feminine idea is somewhat bogus when it comes to applying it to anything other than humans. But it is a short hand for "curves vs angular" in terms of aesthetics.
Flowering and fruit trees are usually treated as "feminine". Pot choice should be made to complement the tree for the season it will be most often put on display, either public shows, or brought into the home. The colors should not match the flowers or fruit, but rather compliment the flowers or fruit. The exception is when the tree will be shown without flowers or fruit. Then the color chosen can be a "Stand In" or a hint to the color of the flowers or fruit. For example, your ginkgo has beautiful yellow foliage, the pot you have with just a splash of yellow, serves to remind the viewer of the yellow that will be there in autumn.
Anyway, if this tree were mine, I would first air layer that nice trunk off those god awful ugly roots. Get a nice radial nebari going. Then I would find a larger diameter oval that is a little shallower than the current pot. The colors I would go for would be in the greens and blues, to complement the beautiful red or orange-red berries. You want to make the color of the berries pop. That is what I would do if it were my tree.
Now I do know Darlene, that you really like ungainly, exposed roots, that is your trademark. I seriously do not expect you to air layer this tree. I expect you to keep the roots the way they are. Its okay, you don't have to explain why. But do consider a lower, wider pot, preferably green tones, or blue tones, possibly with jewel tone highlights in the glaze. Because against the bright color of the berries, flashes of jewel tone colors in your pots would be acceptable. Avoid terra cotta colors, as they are too close to the orange-red colors of your fruit. You want to contrast and highlight the fruit, not down play it by matching the color family of the fruit.
No thought other than the trunk was applied in this photography.
