seed/flood fill recolors all of the pixels that are the same color instead of just an area?

hey im making a seed/flood fill script for my ROBLOX PAINT game

but the thing is: it fills in everything

then it gets REALLY laggy (ive kinda fixed the laggy part with a 'break' thingy)

i think its just this part because it seems to ignore the position for the most part:

if  (frames[i][3]==frames[frame1][3]-1 and frames[i][1].BackgroundColor3==bcolor) or (frames[i][2]==frames[frame1][2]-1 and frames[i][1].BackgroundColor3==bcolor) or (frames[i][3]==frames[frame1][3]+1 and frames[i][1].BackgroundColor3==bcolor) or (frames[i][2]==frames[frame1][2]+1 and frames[i][1].BackgroundColor3==bcolor) then

but heres the whole thing if u think its something else:

function fill(frame,bcolor)
	local frameX = 0
	local frameY = 0
	local frame1 = nil 
	for i=1,#frames do
		if frames[i][1]==frame then
			frameX=frames[i][2]
			frameY=frames[i][3]
			frame1=i
		end
	end
	repeat wait() until frame1
	for i=1,#frames do
		if frame1 then
			--print("jesus christ does this work")
			if  (frames[i][3]==frames[frame1][3]-1 and frames[i][1].BackgroundColor3==bcolor) or (frames[i][2]==frames[frame1][2]-1 and frames[i][1].BackgroundColor3==bcolor) or (frames[i][3]==frames[frame1][3]+1 and frames[i][1].BackgroundColor3==bcolor) or (frames[i][2]==frames[frame1][2]+1 and frames[i][1].BackgroundColor3==bcolor) then
				frames[i][1].BackgroundColor3=color
				fill(frames[i][1],bcolor)
				print("filled")
				break
			end
		end
	end
end

thanks!!!
