The names and pictures of the Unit's foreign advisors who recently joined us are now shown on the homepage of our official website. Prof. Lindsay MacDonald, Dr. Athanasios A. Tsoutseos, Prof. Dr. Stephen Westland, Prof. Alain Tremeau, Dr. James Nobbs are all high-profile colour scientists who do not need any introduction. The presentation brochure of the Colour Science Research Unit contains their confirmation letters shown in order of receipt.

The presentation brochure of the Colour Science Research Unit was released last week and some copies were already distributed to the members of the Department of Imaging and Printing Technology. The brochure contains information about the Unit's research projects, equipment, services, products, members and advisors (who are well known names in the international community of colour scientists).

Excerpts from the positive reviews received for the "Complete Study of Traditional Thai Colors used in Mural Paintings. Traditional Thai Color Name Dictionary.":
•"This work about identification of traditional Thai colors is very important for temple art preservation and has never been done. An important work has been done to retrieve colors corresponding to traditional Thai color names. In this article is explained in details a method to turn a scanner in colorimeter, with most of the tables and references related to the demonstration. As it is an interesting, work, it should be more detailed in a separated article. In the presented article, this scanner work is not mentioned in the title and will not be retrieved by people searching such information."
•"This article presents a research about identification of traditional Thai colours for restoration of mural paintings. The beginning of this research was published online in CRA in November 2011: 'Identification of traditional Thai colours used for mural paintings and Khon masks'. The article we review completes this previous one with an improved identification method and by adding some data. The improved identification method describes the use of a scanner to calculate the average L*a*b* color of a painting that is inhomogeneous, and the way to match it automatically with Munsell patches and NCS dictionary. This part is interesting and described in details. It could be useful for the numerous people who ever wished to turn their scanner into a colorimeter. The other main data added to the previous publication is the Thai colour name dictionary chapter, where are described color names, with explanation about structure of Thai language and colors that were identified or not. This part is interesting as this work was never done before and is important for history and art memory, and it could help for identification in temple and so conservation. The last chapter presents a plan to help painting restoration in situ with photography and application of the Thai color dictionary."

The opinion of Prof. Dr. Lindsay MacDonald, Executive Committee Member of the International Colour Association, about the traditional Thai colour study and Trichromatic Colour Analyser software: "I found Dr Pitchayada's research very interesting and relevant and I believe a great credit to Thailand."

The following digitized dictionaries have been created so far for the Trichromatic Colour Analyser System: Munsell-scan color dictionary, NCS-scan(license-based) color dictionary and Resene®, Crayola® and NBS-ISCC sRGB colour dictionaries, as well as spectral measurement based color dictionaries for the Munsell and NCS(licensed) color systems. As of this year the focus will be set exclusively on the development of the TCA Lab-pack version of the Trichromatic Colour Analyser. We simply do not have the time anymore for the demanding multi-version support we performed so far. A status update is already placed on the product's page at:
TCA LabPack will be continuously developed to be used in several applications. We use it now in the funded project "Novel method for monitoring the developing of browning in fruit and fruit juice".

Trichromatic Colour Analyser Software System benefits of a free license obtained from NCS Colour AB to use in analyzing and identifying the traditional Thai colours. After completing the research, Per Jutterström ( Area Sales & Project Manager - Middle East, North Africa, Japan) wrote: "this kind of activities is what we really like to be involved in for the future so please keep that in mind for next time."
