Gant chart based on matrix table with progression

[m4xon]

Hello,

I'm working on the Gantt chart based on the matrix table and would like to achive something like that with the colours, so in general from the first date to second I have one colour and then from second to third another one:

At the moment I have a measure that gives me 1 numbers during the whole project, but I was wondering how to divide it into several numbers like: first stage = 1, second stage = 2, then I would be able to dd conditional formatting:

CF Gantt = 
VAR StartDate =
    CALCULATE (
        MIN ( dimE[Epic Start Date] ),
        REMOVEFILTERS ( 'dimDate' )
    )
VAR GoDate =
    CALCULATE (
        MIN ( dimE[Epic Go/NoGo Date] ),
        REMOVEFILTERS ( 'dimDate' )
    )
VAR EndDate =
    CALCULATE (
        MIN ( dimE[Epic End Date] ),
        REMOVEFILTERS ( 'dimDate' )
    )
VAR ProjectPeriod =
    MIN ( 'dimDate'[Date] ) >= StartDate
        && MIN ( 'dimDate'[Date] ) <= EndDate
VAR Result =
    IF (
        ISBLANK ( StartDate ),
        BLANK (),
        IF (
            ProjectPeriod,
            1
            )
        )
RETURN
    Result

 
Data model look like this:


Is it even possible?
