Client had a color scheme of maroon, purple, yellow, orange and, for contrast and pop, white. It was for a members event for a health club.
The maroon is a challenge in balloon colors and the closest is a jewel burgundy. The “jewel” indicates it is translucent.. see-thru. This might be called “crystal” in other brand balloons.
All balloons oxidize and will cloud over and develop a matte finish over time. How long it takes depends largely on sunlight, heat and humidity but it happens indoors in climate controlled conditions as well.
These colors can be used to represent stained glass or candy.
