Sofa cushions changed colour

[CLW0502]

Can anyone help me please who has had experience of this. I washed my sofa cushion covers in a non bio detergent that has optical brighteners in it (didn’t realise the implication of this to begin with)

The sofa cushions are now a different colour to the frame, they are duller and greyer in colour whereas the frame is a warmer creamier sandy beige tone. Is there any hope for getting them to re match or do I have to live with it. Realise it’s definitely first world problems however it’s irritating to look at 😄

Optical brighteners have effectively bleached it. Is there a dylon machine dye that matches the colour you want ?

I have found one called sandy beige however I am worried it will then look hugely different to the frame and then there will be no coming back. I did wonder whether scrubbing the frame in the same detergent solution used on the cushion covers might make the difference even out??
