My preferred colour of gloss paint for interiour doors, frames and
skirting boards is pure white. The big disadvantage however, is that
pure white oil-based gloss always turns to cream after a few years. Is
there a one-coat white gloss that does not discolour with age?
Alternatively, is there a light-coloured gloss that still looks good
after it has age-discoloured (other than cream or magnolia)?

Thanks
