Choosing primary and secondary colors.
The primary and secondary shades that you choose for your website serves a lot in your appearance among your users.
The simple trick for choosing either is -
Primary Colors - Should be warm and deep colors instead of joyful colors like green, orange, etc. The objective of primary colors is just to form a foundation for your secondary colors.
Secondary Colors - Should be a contrast, that is exactly opposite to your primary ones. It should not happen that the secondary and primary mixes up, making user's visibility minimum. They should appear at much more height Z-axis in front of your background.
Additional contrast colors - You can add more additional colors that are not exactly opposite to secondary colors, but within a shade of them.
You can prefer any color wheel, and pick
Primary - Soft, Non Vibrant
Secondary - Opposite to primary colors on the wheel
Additional - Within vicinity of secondary colors
