While this blog post tells of solving a very specific problem, the issue of Stuff Hiding In Plain Sight is certainly not unique to WordPress code.
R. Bhavesh recently release a very elegant, professional style, free WordPress theme called WP Premium. I really like it and have installed it on two WordPress blogs, (with a few minor hacks).

It is available in three color schemes, and changing out the color scheme is quite easy.... except it took me about 5 hours to see it. Duh.
In case anyone else needs a hand, here are my notes:
Download and install WP Premium. Here's how to install a theme, if this is new to you.
Sign in to your WordPress account. Click the Presentation tab, then click Theme Editor

In the list of theme files, click stylesheet

Here's the part that tripped me up. Bhavesh's instructions say

See it? I didn't. I keep reading the actual line of code as part of the comment. In the image below, I marked the * and / indicating the end of the comment in red.
The one line that needs to be edited to change the color scheme is immediately following the comment. I've highlighted in in yellow.
To change the color scheme, you simply substitute the word "black" or the word "brown" in place of the word "red" in that one line.

And no, you don't need to search through a whole page of code, it's right up there at the top.

thanks for the heads up on this theme. took it for a test drive and downloaded it. very nice! thanks again!!! :)
