Conditional formatting of stacked bar chart

[Bilal_Niazi123]

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
