I am in the midst of a never ending home renovation.... one that keeps stopping and starting as we run out of budget. it is about to ground to a halt again but after the plasterers have been so i have some wall to paint! Thing is its hallways. When the downstairs was done we use Farrow and Ball paint because I love the fact you can touch it up without painting a whole wall. But now we are on to going up the stairs and into the upstairs halls and I don't have the budget for F&B I don't think. it is a huge area. Do we think I could colour match and it wouldn't be noticeable or do I have to wait? What are other people's experience with pale F&B colour matched paints? I've had bad experiences with v dark exterior ones....
