The envelopes were hand written and the postage stamps were colorful commemoratives, so that it looked more like a personal letter than a business solicitation.

I create a new one for every project that captures the information I need for that project...here is an example from a recent project that I completed:http://www.123flip.com/wp-content/uploads/WI1_House/WI1_Budget_Final.pngDuring renovations, the spreadsheet is my estimated budget, and things are color-coded based on whether I have a firm bid, whether the work is completed yet, how much I've paid, etc.

Or is just matching the color okay?

Also, I used same interior paint color for all of them, saving me the headache when I have to repaint.

I've had mostly good luck with color matches at Sherwin Williams, especially in the whites, tans and grays.

We need to change the ugly green color of our garage DOOR at our rentals.

Same stucco color, same trim color, same attic vent.

I would absolutely love to have a standardized paint color scheme or standard list of colors, but I havent gotten anywhere close on that.

Tile in an earth tone color, is a final solution installed properly.

Most of the time, water moves through the main service line fast enough that water won't pick up much color, and the accumulation of rust flake is lower than in end-point spots - for example, a bathroom sink might only be used twice per day, so those galvanized pipes have water sitting dormant for a long time, whereas every time you use water you wash the pipe to some extent.
