Thanks for feedback and ranging.
At a peacock beautiful feathers.
On each feather there is a pattern.
This pattern can be perceived as ornament (feature, diamond of a peacock).
Central part of a pattern (his heart) and trunk of a bird of blue color.
Therefore color of a brand I choose the blue #84.
On the other hand feathers (most beautiful part of a peacock) the green #85.
Therefore color of a brand can be and green.
The body of a bird is represented in negative space for the best concentration of attention on feathers (diamonds).
Over the head of a peacock a crown, thus a peacock - the queen of jewelry.
I am ready to consider your wishes.
