Well for windows and doors you'd use gloss or satin finish paint in white and it shouldn't really be different to your white wall paint in colour , if you used the same shade of white from the same company.

Thank you IDUS Furniture store for looking into my query.I have a doubt ,if I paint my front wall where those 2 chairs are kept,is it mandate to paint a L shape wall behind sofa? if yes, should I be going with the same color as the front wall? Just FYI- I have a brown and beige ceiling and was planning to paint my bedroom doors with darker shades

The potential yellowness discernible in Simply White is because it is actually a more colourful white from the Yellow Hue Family. That little kick of colour can work well on ceilings, as that plane can often make a colour appear a little darker & more greyed anyway. So sometimes a choice of more neutral greys here have a possibility of ending up a little grey & shadowy. This is obviously dependent on the available light. Chantilly Lace is a more neutral white from the Green Yellow Hue Family. In character in balanced light it can appear ‘just white’, but in some light people see a hint of its inherent greenness, some might even read it as blueness. Again depending upon how well balanced the available light is. Super White OC-152 is that bit more neutral & so could read a touch more crisp again. Many people prefer a more neutral, crisp trim. It can give you more options for alternative wall colours, should you decide to repaint down the line. Neither Simply or your trim choice would be sat next to each other though, as the wall would come between them. I think the biggest concern would be sitting Simply White next to Classic gray for the reasons mentioned before. If you are set upon Classic Gray then I would repaint the ceiling and swap to one of the more neutral options. I would shortlist your line-up and sample upon board or lining paper in your space so you can move them around.
