Tricolor is a combination of saffron, green, and white. So, to bring the right shades, add colors with the appropriate amount.
Not all sweets can be made into a tricolor theme, so choose the right sweet recipes that can hold up color and shape.
Make sure all the layers of layered tricolor sweets are even and well distributed to not disturb the color balance and shape.
When using different flavors for each color, make sure the flavors complement each other and not cancel out.
For making perfect layered desserts like mousse and parfait, make sure each layer is clean and set properly.
