Sorry. Trying this again:

shared watchlist column script: http://tos.mx/tFVEHIU Click here for --> Easiest way to load shared links

AddLabel(yes, " ");
AssignBackgroundColor(if close is greater than or equal to MovAvgExponential("length" = 20)."AvgExp" then color.green else color.current);

# Define the length for the exponential moving average
input length = 5;

# Calculate the exponential moving average
def ema5 = ExpAverage(close, length);

# Set the background color conditionally
AssignBackgroundColor(if close >= ema5 then Color.GREEN else Color.CURRENT);

# Plot the exponential moving average for reference
plot emaLine = ema5;

I have this code, but how do I make it the WORDS color in black? the current one is white color, is hard to see.
