Button Design (Pastel colors)

What are pastel colors?
It refers to light colors that are not clear shades like primary colors (red, blue, yellow, green, etc.) but are mixed with white, such as cherry blossom or wisteria.

Depending on the nature of its role, a button may or may not have to make a statement about itself. Pastel colors are in the neutral color category. They are the perfect color scheme to show that the button is "present" while not being "too assertive".
