I use the Hot Pink color. Even with the just pink color you should be fine. There is no need to worry about TA unless your PH starts bouncing around and with your reading you should be in great shape.

Remember, don't micro manage your pool. Each pool water is different.

Here is a perfect example: My pool water's CA is in the upper acceptable range (for people who have to worry about CA). Yet, when I shock with powdered shock (Cal Hypo), my pool will get cloudy. When I shock with bleach, it doesn't happen.

What kind of pool do you have? This dictates ranges like Calcium.
