Background formatting in the table based on segment

[gumis_rulez]

I am using folllowing measure to choose transport_ids for current day and arrival time.

Tooltip = 
CONCATENATEX (
    CALCULATETABLE (
        VALUES ( 'Direct 03 10'[Route name] )
        
    ),
    [Route name],
    //","
    UNICHAR(10)
)

The measure works perfectly but would like to add another feature. Each transport_id belongs to one of the three segments. I would like to have in the table below each transport_id background formatted acc to the segment it belongs to. It would be easy if for example for Monday 18:00 there would be transport_id's which would belong to one segment. But it happens that for one particular date and time there might be three transports and each would be a part of different segment, so each should have different background colour. How to achieve this? I beleve concatex will not work in this case.

1. no need for CALCULATETABLE

Tooltip = 
CONCATENATEX (
    VALUES ( 'Direct 03 10'[Route name] ),
    [Route name],
    UNICHAR(10)
)

2. You would need to use SVG to render different colors inside a matrix cell, and do all kinds of rectangle gymnastics
