The moon is essentially grey… no colour

Moon_apollo12This quote from astronaut Jim Lovell on board Apollo 9 was rather a stark reminder of the reality of space. No colour. We are so used to the colour of life on earth, the words Lovell spoke when first seeing the moon close up highlighted the truth that without light there is no colour and as the moon only reflects about 13 percent of light from the sun it is, in reality not colourful.

Basics of Colour Matching

Here at ColourServe we are aware that there are many outside influences that can interfere with the
colour matching process. As part of our commitment to top quality service and support we will provide
a weekly update on the the basics of colour matching, starting with the all important Viewing Cabinet.
Correct Method of Viewing Colour Samples:
1. Light source. Standardise on a light source suited to the environment in which the finished products is to be seen e.g. D65 (daylight). Make sure only this reference light is used for communicating colour and matching colour, although others can be used for specific other reasons e.g. identifying metameric materials. All lamps should be checked and replaced annually.
2. Internal paint colour. Standardise on an agreed paint e.g. G5574, Munsell N5 or N7 and ensure the internal surfaces are re-painted annually.
3. Observer viewing angle. Observers must view samples from an agreed angle e.g. 45 degrees. Check observers know where to stand to achieve this.
In addition:
No other objects within the cabinet
Samples must be places at the back of the cabinet and must be touching
Lights in the room being used must be switched off and no direct sunlight
No reflective clothing to be worn when assessing the samples

Next week we will talk about the Ishihara and Munsell 100 tests along with the importance of these in within the colour industry

Blue for you?

Blue Jeans (Closeup / Nahaufnahme)Here is a great post on Munsell Color Blog about colour control and the challenges therein within the dyeing and specifically indigo dyeing industries. Denim jeans are notoriously difficult to measure in terms of colour; perhaps the reason so many people love them is because the colour and textures vary so much, but there has to be a degree of control in such a large scale production environment. The most interesting comment in the post is that about the lack of understanding in textiles industries as regards colour. Although many large companies in this huge industry spend a fortune on hardware and software to measure colour, they skimp on training, or are let down by colour instrument manufacturers when it comes to support and training.

People are the most valuable asset of most businesses and it is people who are they key to getting good commercial decisions when colour matching in textiles.

Fastest colours: thanks to Trimite

thrust 2-2The 4th October 2013 was the 30th anniversary of Richard Noble’s land speed record with Thrust 2 at a speed of 633.468 mph. Worthy of mention in it’s own right, but for us particularly as our good customer Trimite Global Coatings was a main sponsor and one of the so-called “super seven” sponsors who came to Noble’s aid at the eleventh hour with additional funds to keep the attempt alive.

Colour and mathematics

20130902-115335.jpg Although not specifically about colour, this post is a fascinating example of the link between colour science and mathematics.

The four colour theorem uses colour to illustrate a maths topic visually. Interestingly, colour science works the other way around, using mathematical equation to quantify colour. One may argue colour is not an exact science in certain applications, and indeed this is so. However, the maths behind colour science allows one to use a combination of data and visual assessment to reach a reasonable conclusion.

Most important, the four colour theorem makes one think laterally: colour = maths, maths = colour, which is why we love it..
