Coloring RSI line

[Getone]

Can someone fix the following code for me? I want to assign the color to the value instead of the background and I would Also like to color RED the values 85 and greater.
Thanks-

plot X = round(RSI(4), 0);

assignbackgroundColor(if rsi(4) < 15 then
color.green else color.current);

X.assignvaluecolor(if rsi(4) < 15 then color.black
else color.current);

declare lower;

input rsi_len = 4;
def r = RSI(rsi_len);

input rsi_lo_lvl = 15;
input rsi_hi_lvl = 85;

plot X = round(R, 0);
X.assignvaluecolor(if r < rsi_lo_lvl then color.green
 else if r > rsi_hi_lvl then color.red
 else color.gray);

plot z0 = 50;
z0.setdefaultcolor(color.white);
