Legacy GM Change Color Issue

[EdTheDog]

Hello! I am trying to make a program that draws pixel by pixel but for some reason, I can't change the color?
Here is the code:

DRAW:

draw_self()
draw_text(room_width/2,room_height/2,"O")
if(global.drawdot = true and global.penon = true)
{
    surface_set_target(surface);
    draw_set_color(color)
    draw_point(x,y)
    surface_reset_target();
    global.drawdot = false
}

CREATE:

color = c_black
global.drawdot = true
global.penon = true
surface = surface_create(room_width,room_height)

STEP:
if(keyboard_check(ord('R')))
{
color = c_red
global.drawdot = true
}

It starts out drawing black pixels just fine but when I press R it doesn't draw pixels anymore. As a test, a draw an O in the center of the room and that changes to red just fine. Any help is appreciated!
