Sometimes its difficult to combine colours especially for an event, where people from different backgrounds, different social status, different tribes and toungue will be gathering with their EYES WORKING WELL.
You just have to give that event that spectacular touch. I've placed some examples and I'm sure it'll help you combine your colours well.
Brown
Mint green
Orange
There are also other colour combinations like
Baby-Pink and wine
Yellow and dark orange
Fucial pink and Turquoise blue
White and Red
Combination of light and dark shades of peach
lilac and purple
Sea blue and Navy blue
Grey and Black
I'll take time to seperate colours for different moods and types of events. Pls stay right here. lol!!!!!
