I was acknowledging your thanks..... I'm surprised with your reaction as well...lol... unless you wanted more info of why and how did that work.... Nothing's wrong with you... It's a curiousity of a newbie and that is good - you learn more thoroughly...... no biggie...
Select color range , as the name suggests, selects a color's range or spectrum depending on your settings and what you select. Say u select red, it will select all pigments of red in the image - from light to dark.... Tho there is a sort of drawback, most especially if the color you select blends into another color. Hence , some of the pixels next to it will be included in the selection. .... smudges or slightest pixel dots of red, magenta, pink, even orange....... and when deleted, leaves you with a dead or dull color...
In your case, the logo layer was a straightforward white with black or dark smudges . Had you chosen white, Color Range would have selected all the shades of white and when deleted leaves you with black and slight dark smudges. and I suspected you only had 2 or 3 solid colors in your logo....
This is something I always say .... There are many ways to doing a certain task in PS.... I could have suggested the magic wand ... It will also do but may affect the G-clef in ways that may not be as expected.
And I have to say that my procedure may not work in other situations all depending on the image at hand. Had the conditions of your image been different, you may have to use acekin's suggestion. Or even Steve's.... Or other suggestions if ours fail. But we didn't know how to help unless we see what's in your monitor.
My moral of the story... The more you know about the individual functions of PS and the limitations of these functions, you will be able to figure out what move to take.....
Hope this helps you.... keep seeking and you will find.....
