Blend color in photoshop

Hi all,
I'm being confused about the blend modes in photoshop.
In this link: http://help.adobe.com/en_US/Photosho...b64-77eaa.html they mention the blend color. There really is an explanation but I still can't understand how we can indicate a blend color. I need some concise explanation for this.

And by the way, do you guys have any experience in using the blend modes? It's nice if you could share.

Thanks in advance :)

The blend modes in Photoshop, this is a very simple guide it does take a lot of time before they come automatic to you.
1 will darken the layer below
2 will lighten the layer below
3 will add some contrast to the layer below
4 will invert the colours to the layer below
5 will effect colours etc. to the layer below
6 is the Opacity or strength of the effect.
A real life example that I have used thousands of times is to duplicate the background layer, then change its Blend Mode to Soft Light to increase contrast in a natural way.

try blending black and pink or navy with white
