I'm trying to add two clouds to an indicator but one cloud(the lower one) automatically displays in red color on the chart no matter what color I type in. For example, in the script below, I have violet as the color of my choice, but the chart displays it in red. Is this a thinkorswim default or is there something wrong with the script? Is there any way I can change it or have the indicator display the color I want? Thanks in advance.

-------------------------------------


input length = 20;
input Fib1 = .25;
input Fib2 = .75;

plot topBand = Highest(high[1], length);
plot bottomBand = Lowest(low[1], length);
plot centerBand = (topBand + bottomBand) / 2;
plot Fibo1 = ((topBand - bottomband) * Fib1) + bottomband;
plot Fibo2 = ((topBand - bottomband) * Fib2) + bottomband;

AddCloud(topband, Fibo2, color.green);
AddCloud(bottomband, Fibo1, Color.violet);

got it figured out. I had to change the last line of code so the two variables are swapped:

previous: addcloud(bottomband, Fibo1, color.blue);

now: addcloud(Fibo1, bottomband, color.blue);

I don't know why that works but it does!

Whichever value you put first is the "top" value.
Second is the "bottom" value.

So, whichever color you place first after that displays when top is top and bottom is bottom.
If those flip (where the first value is below, and the second is above), the second color displays.

By default, the first/second colors are green/red. You don't have a second color, so, when you flipped the values, the colors flipped.

Make sense?
