hello, i hope someone can help me.
I'm designing a retail store re-furb. all the stairs and floor finishes will be replaced.
I've heard people saying the building regulations state that i need to have contrasting colours on each landing and final steps (for partialy sighted people)?
is this true? i cant find anything in the regs.
i know you have to have contrasting nosings, but didnt know aobut the steps.

say i has a grey ground floor, and wanted green stairs (with a landing) going up to a green mezzanine floor, would this be ok?

If you are proposing a grey floor and green steps, then yes... that will be acceptable.

As per AD M, the difference in light reflectance values of the two surfaces is greater than 30 points. The AD also asks you to refer to...

"Colour, contrast and perception. Design guidance for internal built environments" (Published by Reading University).
