How external elements can effect colour choice.
Something important to consider is that colours can change under different external conditions. For example I chose to paint the exterior of my house grey, for all intents and purposes this would seem quite straight forward. The only tricky thing would be to choose how light or dark I wanted the house to look. Not so!
When I started to look at the different greys available there is quite a range.
With my first choice "Dulux Timeless Grey" although the colour chip was the right tone of grey, when I painted the sample colour onto my house it became quite green. This was because I live in a valley and as the sun hits the valley on the other side it reflects a green hue back. To balance this I had to choose a grey with a much warmer hue in it.
After many sample pots I came accross a house that had the exact colour I was looking for. As I was talking some pictures of the house to try and work out what it was the owner of the house came out. I smiled and said hello and luckily she was very friendly. She told me they had used a Porters colour "White Rhino."
Porters White Rhino
This was the perfect colour for our house as it balanced the green reflecting from the valley.
Another nice thing about this colour was that even on a sunny, blue sky day the house still looks grey and does not have a blue tint as can be the case with many greys.
You can see bellow how a colour can chance in it's environment.
Our house painted in Porter White Rhino.
Working with interior elements can have the same impact as about. Even the warm tones from a timber floor can have a profound impact on paint colours and the textiles within a room. It is really important to see samples in in the space so you can see what type of colour finish you will get.
Choose your light source carefully!

Every space should have a lighting plan. From a home's interior to an industrial warehouse or a retail shopping environment, each place will have it's own specific requirements for lighting.
In a home situation you may need to use lighting for specific tasks. This image has a pendant light that will light the dinning table up when required. Because of the running costs of a house low energy compact florescent globes should be used here. In the past this would have ment that the lighting would have a cool look, however these days you can get "warm light" florescent globes which give a very nice soft warm light effect even LED light can give a warm feel.
They have also used down lights under the cabinets to light the benches and LED light again with a warm hue could be used here. You can also see lighting within the cabinets. This gives the room a feeling of generosity and all these different lighting effects soften the look of the room.
A large space like a furniture show room will need specific spot lights as the light requirements are so vast. It is very important that the furniture is illuminated correctly or the materials may have a unrealistic colour. When you are buying a large item like furniture it is always a good idea to take a sample home where it is to be used as all light source will alter the colour. Reflected light from wall colours, carpets, floorboards or even the green from the trees outside the room can change to look of a colour.
In smaller retain shops lighting will create a mood. The shop on top here looks contemporary, modern and quite clinical. They have used spot lighting as well as wall which give the clothes the correct amount of light. The lighting they have used is a very cool light. It CCT rating would be quite high, around 5000K. You can also see how light shinning on the reflective black surface can give the illusion of space, almost like a mirrored surface.
The shop bellow has a very different feel. Much more intimate, which is appropriate for a jewelry store. They have used down light and spot lights but they have a much lower CCT rating. It also make a big room seem a bit smaller and the specific task lighting in the cabinets help bring you eye and interest to them.
When there is little or no natural light coming into a space like a showroom, it is important to choose the correct style of light fitting and keep in mind the effects of colour that the globes can have.
