Vibrant colors are pain for an eye. The designers choose those colors only
for attractive.Some eye catchy title, attracting images, promotions
etc..Dark is most of them feel that negative color and sign for bad.
I don't feel that. Even our RGB Garden color scheme also dark. I love
dark.In my experience, vibrant colors are only controlled by dark. Some of
them did it very well.
Here I showcased some designs, that how the designers having the control of
vibrant colors blend with dark.
Nice Web Designs.
