Hi Chelsea, I believe this white colour my be Dulux Whisper White. Keep in mind that the colour you see depends a lot on the photo quality as well as your computer screen. It may look totally different in real life.
My suggestion is to get a few swatches of the colours you are contemplating and then taking them out on site to look at in the natural lighting. This will give you the best result in the end.
There are so many different 'white' colours that it can be hard to know which one to pick. The colour will always look brighter and whiter when it's viewed outdoors in the sunlight than when it's viewed indoors in artificial lighting.
