问题
I had an idea to programmatically generate matching color schemes however I need to be able to generate a linear gradient given a set of two colors (Hex or RGB values).
Can anyone provide me the (pseudo-)code or point me in the right direction to accomplish this task?
EDIT: I forgot to mention, but I also need to specify (or know) the number of steps the gradient takes from color A to color B.

Okay, so you know the steps, start color and end color. Assuming you have RGB values for each color:
red_diff = end_red - start_red
green_diff = end_green - start_green
blue_diff = end_blue - start_blue
#Note: This is all integer division
red_step = red_diff / num_steps
green_step = green_diff / num_steps
blue_step = blue_diff / num_steps
current_red = start_red
current_geen = start_green
current_blue = start_blue
while current_red != end_red and current_green != end_green and current_blue != end_blue:
current_red += red_step
current_green += green_step
current_blue += blue_step
# print color
