The easiest way would be to select all completed cells and format the text
blue when you first open your spreadsheet. To automate the process would
require the incorporation of a date/time cell, conditional formatting, VBA
or combination (depending on existing data).

Is this possible to change text colour(say to blue) after 10hrs
automatically.
so that next day when i open sheet & start working i can easily
differentiate
yesterday's work.

Is there any other way to do this?
please elaborate the process.
