Help with color selection for interiors

Colors always appear different on a surface as well. Unfortunately, I had to realize this now with our facade paint...

RAL is in any case not as clear-cut as Pantone. A color mixed according to a RAL color chart will only ever look "the same" if it is applied again onto the same glossy cardboard from which the color chart is made – and thus will always look different when painted onto plaster.

I would like very light, pale tones. Most of the colors I have seen so far on color fans were all far too dark or strong for me. Even the sand or gray tones.

It seems to me that you are simply stuck on a misunderstanding – namely the difference between solid colors and tinting colors.

I have heard the terms before, but I don't know exactly how to classify them. Just make solid color lighter? Or what is meant by that?

2) Tape off a frame, so the paint does not go up to the ceiling and the adjacent walls.

We just had this topic with our painter yesterday... He said, nowadays nobody makes a frame anymore?!? And he works for a painting company that has already painted the "more modern" buildings in town (restaurants, department stores, architect-designed houses, etc.)...

We once had a thread here where the OP complained that the upper edge of the colored wall was uneven. The reason was that the wall-ceiling was painted up to the edge and no white strip was left.

It works just as well the other way around, without one having to look less good than the other. There is no general taste...

We laid out and displayed all samples (tiles, kitchen fronts, countertop, doors, painter's color card) in the house over 2 days in the rooms under artificial and daylight. The colors individually may fit, but together it is a different picture. My wife gathered all the selected samples during that time and then dutifully returned them.
