Special icon treatments in the Mac Finder

Two things I want for icons in the Macintosh Finder:

# Color-labeling icons in the Finder is OK — but I wish applying a label would wash the whole icon in color or surround it in a colored halo so that it were even more emphatic.
# And speaking of emphatic, I wish I could adjust the size of individual icons in any window (not just change the size of them all).

Digital fridge door

I want a refrigerator whose entire front surface is a digital display, programmable to show pictures, text, websites, anything.
