Heiken Ashi colour change

[blueskypete]

Ive seen that the HA indicator is included. I was wondering if any guys on here would know how to trigger a "colour change" ie. from last candle close (0)? being different colour to previous (1) ? candle ? i just cant seem to work out the logic using the indicator parameters box provided together with the "operators", "price value" etc to make this happen? cheers
