Beware of looking online for colours eg Pinterest. Unless your screen has been set up with profiling equipment and is recalibrated every week, what you see is not what you will get. And the original image is probably not accurate, as digi cameras can make wild guesses at what they think they are being pointed at.
And light is not white. 'Neutral' is daylight around midday. All artificial light sources are way off daylight - tungsten is yellow/orange, fluorescents are greenish. The new bulbs are closer to daylight. So all colours will seem to change when you look at them in different situations. Shop lights are not daylight, you need to take stuff outside to check the colour (NB for clothes).
If you're taking pics to put on eg e*ay it is best to work in daylight - outside or close to a window with room lights off. I've bought white shirts that were green and vice versa, you have to allow for this or take a chance on liking what arrives.
In light of our current weather.......
