TFTLibrary > TFT
Called before drawing an object on screen, it sets the color of lines and borders around shapes.
stroke() expects 8-bit values for each of the red, green, and blue channels, but the screen does not display with this fidelity. The red and blue values are scaled to 5-bit color (32 discrete steps), and the green is 6-bit color (64 discrete steps).
screen.stroke(red, green, blue);
