Change Candle color based on its Volume

Looking for a script for the user to be able to define candle colors for the following:

a bullish candle if the volume is over 1.2x(average 20 day volume)
a bearish candle if the volume is over 1.2x(average 20 day volume)
a bullish candle if the volume is over 1.5x(average 20 day volume)
a bearish candle if the volume is over 1.5x(average 20 day volume)
All other candles user will define the same color

would like so user can pick from color swatches and set transparency

It's 20 day average volume.
Here's my intention so hopefully it helps:

My end goal is to have the 1.5x Average Vol candles really stick out on a chart (both bullish bearish), then the 1.2x Average Vol candles also stick out (both bullish and bearish), but not as intense, then the rest of the candles (all candles <1.2x) almost translucent

can show colored lines after the last bar, like a color legend.
can show bubbles with the volume factor.

i copied color code lines from here,
https://usethinkscript.com/threads/an-example-study-to-show-10-shades-of-a-selected-color.15155/

if you want day candles, set the chart to day. i didn't use 2nd aggregation to make it always day.

That's what I'm looking for, I really appreciate you taking the time to do this!
My only feedback is when I change the color of z1 - z6, it doesn't change the bar colors on the chart.

that's because it won't. that screen is just for plots. not AssignPriceColor()
the plots are test lines, not candle colors.

being a programmer, i have never looked at that screen. i program what i want.
so, maybe someone else has a different answer.
