Colour cells based on date ranges

Hi,

I would like to know if it's possible to colour cells based on a date range entered in start date and end date cells.

My spread sheet (attached) has start date and end date cells and to the right of these each column is headed with the w/c date. My requirement is to enter a start date (for example 21/01/2019) and an end date (for example 22/04/2019) and for the cells that correspond to these dates to the right change colour to show a time line of activity.

Is this possible?

Was thinking conditional formatting with a formula to indicate the affected cells but unable to get close to the requirement.

Any help would be appreciated.
