I Googled this and could not found a chart. Since the various Log possibilities are Verbose, Debug, Information, Warning,and Error, I have a couple of assumptions, but...:
Verbose = ? Debug = ? Information = ? Warning = Yellow? Error= Red?
The letter colors in above diagram are the colors in which log appears
The filter buttons on the LogCat pane in Eclipse are colour-coded to match the colour of the messages, so:
Verbose - black
Debug - blue
Info - green
Warning - orange
Error - red
Edit: a picture reference:

- Error = Red
- Warn = Yellow
- Info = Green
- Debug = Blue (I think)
- Verbose = No color
