Here are some possibilities for you with different color variations.
The small circle/cupcakes are purposely done asymmetrical in the layout.
If your box is khaki and not a printed khaki and the design is silkscreened rather than printed the 3rd color can be white, otherwise if the khaki is not printed white will need to be substituted.
I will check back with you sometime tomorrow afternoon. Hope you have a great weekend Kind Regards, Teresa
