FT800 easy display development

Other Hardware Displays
1

Good morning all,
I have an Arduino Mega 2560 with an FT800 LCD for a airspeed project for an airplane.
I would like to create bands white, green and yellow colors and a red line for the different speeds, but I can't.
Can you help me please ?

Example:
White band between a speed from 50 to 120 km/h
Green band between a speed from 70 to 180 km/h
Yellow band between a speed from 180 to 240 km/h
These bands are side by side
Red line at 240 km/h which is the maximum speed limit

Attached is the Arduino code file.
