Photoshop - Image being saved in different color shade

I'm applying a colour overlay with colour of "#fa2e88" to an image. But after saving it for web, it will appear in another shade on web browser (#ff00e9, which is more saturated and brighter)

I've tried this on different image modes (RGB, CMYK, Lab Color) but the outcome was the same. One other strange things is that when I apply the color overlay and open up the color overlay popup, the color is changed from "#fa2e88" to "#ee3587".

And this is my color settings:

Can someone please explain why is this happening? and what's the solution?
