What's the EXACT color 50% Blue and 50% White create?

Can someone show me an example of the EXACT color you get when you mix 50% blue and 50% white? I'm NOT looking for a simple response like baby blue or sky blue or powder blue or light blue plus those shades look different to everyone anyways.

I'll give props and appreciate it even more, if some one took the time to actually do the half and half mix with their water colors or whatever and then posted the pic on here.

do it on photoshop? make sure your screen set up is right & you should get a pretty close match
or i know in the uk some diy stores mix paint for ya and you can get a tester, so ask them to do it.
