Q. Do you do samples?
A. Yes, all of our samples are hand painted using a matt emulsion and come in a standard size of 4x4”.You can order samples by emailing our Colour Advisory team at PPGExtra@ppg.com and they will send you our Colour Sample Request Form. All samples are dispatched within 5 working days for reasonable requests.
Q. What are Light Reflectance Values (LRVs)?
Every colour has a Light Reflectance Value which represents the percentage of light that is reflected off surfaces; the higher the value, the lighter the colour. It is expressed on a scale of 0-100 where absolute white has a value of 100 and absolute black has a value of 0.
LRV’s become a key consideration when designing spaces to comply with Approved Document Part M - Access to and Use of Buildings. This document outlines the requirements for certain surfaces to contrast with their surroundings. Approved Document Part M suggests a difference of 30 points between critical surfaces is needed in order to assist those with visual impairment to successfully navigate buildings and aid in giving a sense of dimension to the area.
For people with adequate vision, difference in hue or chroma (colour intensity) provides sufficient visual contrast. But for people who are visually impaired, the main feature of a surface which determines the ability to identify differences in colour, is the amount of light the surface reflects.
Q. Can you colour match my X?
A. Yes, you can take your item to your local Johnstone's Decorating Centre. There they will be able to scan your colour using a spectrophotometer which will offer our nearest colour in our range to the item being scanned.
Q. Why does my colour look different?
A. There are a number of factors that can cause a colour to look different to the one you initially selected.
If you are selecting your colour from a website, the final colour you end up with can be very different as there can be a huge variation between how one screen monitor is set up to another. If you are selecting from a colour card, is the colour deposited or printed? Colour cards which contain deposited colours are produced by putting small squares of wet paint pigment onto the colour card; whereas printing utilises the CMYK system and can be subject to variation from one printer to another. If you have painted your colour, you may find that the walls look different depending on the time of day or the light source in the setting that you are painting in.
You should always choose colours in the location you are going to be painting, so that you can see exactly how the light influences the colour. North facing rooms can make colours look cool and bluish; whereas East facing rooms have warm light in the morning, but this light turns cooler in the evening.
We suggest that you obtain tester pots or samples which allow you to paint a small space and experiment with different options for a while before making a decision.
