How to make the opening 6 histogram bars a different color from the rest of the day?

Hi. I cannot figure out how to create a solution. Would GREATLY appreciate your help.

I created a simple volume indicator for my chart to watch some market internal metrics. I'm trying to get the first 6 bars of this volume chart to be a different color from the rest of the bars in the chart. Basically, I want the volume bars in the first 30 minutes of market open to be a separate color form the volume bars the rest of the day.

However, I'm not attached to the bars themselves being a color. I'm open to simply shading the background of this indicator during the first 30 minutes of market open.

I've attempted the above without success. I've also attempted drawing a vertical line 30 minutes into market open without succss.

I think the code I'm struggling with is time based code, making something happen just in that first 30 minutes of market open. All my attempts have failed. Any guidance or code to solve this problem or point me in a correct direction would be apprecaited.

Including a google drive link to a screenshot of the chart with the indicator I've coded. Have drawn a yellow box around the 6 candles I want to change the colors on every day. https://drive.google.com/file/d/1uYcfh6gosC2OQ_P2s9-39PusdhoMu4Zu/view?usp=sharing

Thank you SO MUCH in advance for your help

Best,

This should help

def range = secondsFromTime(0930)>=0 and secondsFromTime(1000)<0;
plot volr = if range then volume else double.nan;
volr.setdefaultColor(color.white);
volr.setpaintingStrategy(paintingStrategy.HISTOGRAM);
