Conditional formatting of stacked bar chart

Hi, I have a stacked bar chart where I want to apply conditional formatting.
The y-axis is 'Job Name' and the x-axis has all numeric columns that are showing the number of days. I want to apply conditional formatting of these number of days columns. For example,

if 'opened - sent' <12 then the bar color should be green otherwise red.
if 'Sent - 1st interview' < 5 then green otherwise red
if '1st - 2nd interview' < 5 then green otherwise red
and so on...

Kindly check the attached image to get the clear picture of my requirements.
Any help/suggestion will be appreciated.
Thank You
