legend() does not support an argument to change the text color, so you
have to change the plot parameters prior to calling legend():

# Draw a quick plot
plot(1:5)

# Save the old text color value
col.old <- par("col")

# Set the text color to white
par("col" = "white")

# Draw the legend
legend(1, 5, legend = "Text Goes Here", bg = "black")

# Restore the original text color
par("col" = col.old)
