Illustrator colors are more vibrant than when exported
When working in illustrator my colors look much more vibrant than when I export. In this example, files I am working on color mode is set to RGB and profiles are set to sRGB. I get the colors how I want in illustrator, but when I export the colors are much darker.
In another exapmle, the same thing happens with CMYK. I am working on a file that is CMYK for print and the file in illustrator is very bright, but when saved as PDF or previewed in finder the color is much darker. It also prints darker than what I am seeing form illustrator. I have tried printing from both a PDF and staright from illustrator and both come out darker that what I see on screen in illustrator. 
I am having to use Pantone swatches or brighten things and test eport/print until the color starts to look correct because I have no way of knowing what the color will export or print like if I just create the color in illustrator that I want. This is adding a lot of time on my projects, please help!
