How do I change shiny spinda's spot colors?

[Wombatius]

I would just like to know how to change specifically shiny spinda's spot colors to match the custom shiny I made.

It is defined in def pbSpindaSpots(pkmn, bitmap).

if pkmn.shiny? #The last three parameters decide the color of spots.
    drawSpot(bitmap, spot1, b + 33, a + 25, -75, -10, -150)
    drawSpot(bitmap, spot2, d + 21, c + 24, -75, -10, -150)
    drawSpot(bitmap, spot3, f + 39, e + 7, -75, -10, -150)
    drawSpot(bitmap, spot4, h + 15, g + 6, -75, -10, -150)
  else
    drawSpot(bitmap, spot1, b + 33, a + 25, 0, -115, -75)
    drawSpot(bitmap, spot2, d + 21, c + 24, 0, -115, -75)
    drawSpot(bitmap, spot3, f + 39, e + 7, 0, -115, -75)
    drawSpot(bitmap, spot4, h + 15, g + 6, 0, -115, -75)
  end
