JavaScript: Making color lighter

HTML Code:

---

<label for="biz_name">Bussines name</label>

---

Color and all other properties for label element have been set in external CSS file.
Minimizing markup!

I need a JS script, which will:
a) get activated / triggered when label element is being hovered.
b) obtain a color of label element.
c) make that color lighter, of that label element (no matter what color is in question)

Color is hex! :wave:

What's so hard about this? All you will be doing is using the onmouseover and onmouseout events mixed with a custom JavaScript function. In that function, use parseInt(x, 16) to work with the hexadecimal numbers.

Problem is that I don't know, "how much" should I add or subtract from current color, to make it lighter

Any amount you add will make it lighter. Just play around with the amount until you get results you like.

Ok, thanks!
