What does the three color bar graph mean?
I am unsure what you are describing? Is this for PC or mobile (app) version?
On the mobile version the little bar that is beside your name on the main screen is blue and black and represents the progress toward your next level. A sliver of blue means you have just started into the current level and a sliver of black means you are almost to the next level.
Is that what you mean?
