SummaryA simple technique for determining the preference of houseflies for surfdces of various colours is described. This consists of liberating adults into a Peet·Grady testing chamher fitted with movable coloured corners. The numbers of flies rest· ing on the coloured corners are recorded at intervals to provide adequate data for comparison.The ascending order of preference for the particular colours lested was white and sky hlue (equal) ,light grey, green, yellow and medium grey (equal), dusky hIue, and red. From measurements of the visual reflectances of the various colours it was found. that the order of preference could he explained. largely hy a reaction to the intensity of the light reflected hy the coloured surfaces, darker surfaces heing preferred to lighter surfaces.

“…The fading of the paint panels exposed in the two machines was more rapid than that of the panels exposed outdoors, for two reasons: (1) the flux of the energy incident on the panels was at full density whenever average midday sunlight (8) (from Moon [9] using air mass of 2.0).…”

Ability to resist fading is a valued property of most paint and textile materials, and therefore improved methods for measuring the course of fading are in demand. Two of the important evidences of the fading of paints, namely change of color and change of gloss, can be measured rapidly by photoelectric methods developed within the past few years. In the present study photoelectric tristimulus measurements of color change and photoelectric measurements of specular-gloss change were used to follow the fading of several paint samples exposed both to outdoor weather and to two machine treatments (A and B) designed to weather the samples at an accelerated rate. With these measurements it was possible to compare numerically the rates of artificial and natural fading of the paints. The data which were obtained show: (1) the treatment used in conjunction with apparatus A caused fading which averaged 20 times as fast as fading outdoors, but the speed-up factor varied from roughly 5 times for one paint to roughly 40 times for another; (2) the treatment used in conjunction with apparatus B caused fading which averaged 5 times as fast as fading outdoors, but the speed-up factor varied from roughly 3 times for one paint to roughly 20 times for another; and (3) for almost every paint tested, the factor relating the speed of fading from treatment in apparatus A to the speed outdoors was more nearly constant through the whole fading process than the corresponding factor for treatment in apparatus B. Thus treatment A not only faded paints faster, but it provided a preview of the course of fading which was usually a better representation of outdoor fading than that provided by treatment B. The data collected during the present study are noteworthy chiefly for the methods they demonstrate. These should be valuable for future studies of the fading of materials and for the examination of methods for accelerating fading.

“…The process of conversion is the reverse of that described in section III, 5. The ISOC-NBS color designations in the last column were found from these book notations in the usual way [18], except that a number of samples that fall on the boundary between two color designations have been given a single rather than a double designation by carrying out the conversion to Munsell book notations to one more decimal place than is given in this table.…”

“…This standard was intended primarily to assist subcontractors to comply with color requirements by providing a unified set of coordinated procedures for color specification. The standard provides (1) that the spectrophotometer shall be re(,ognized as the basic instrument in color specification, (2) [25] be used wherever applicable, and (4) that if a color designation is requ~ed for general comprehensibility, with precision unimportant, the IS!JC-NBS method of designating colors be used [18]. , The specification of the colors of the ninth edition of the Standard Color Card of America and of those of the United States Army Color Card has been undertaken for the purpose of ronelating these textile standards with the general methods covered by Z44-1942.…”

The color c ards of the Textile Color Card Association of the United Stat es are widely used i n the textile and a lli ed industries and by many p rocuring agencies o f t h e Federal Government. The Textile Color Card Association issues both seasonal and standard color cards. The seasonal car ds p rovide a color-fo recastin g sery ice to textile manufacturers and promote color coord ination am ong t h e t rades; the standard cards present colors for which there is a popu la r and continuing demand. Most impor tant of the color cards is t he Standar d Color Card of Ameri ca, the current nint h ed ition containi ng 216 colors. Preeminent amon g t he m a ny special sets of color cards iss ued by t he Association for use of the Federa l Governm ent is t h e United States Army Color Card showing 22 official colors for the arms and services. T he specification of the colors of t he Ninth Edition Standard Color Card and the Un ited States Army Color Card h as been undertaken for the pur pose of correlating these textile standar ds with American War Standard Z44-1942 for the specification and description of color. T he 238 samples comprising these color cards have been examined by basic spectrophotometric and colorimetric procedures. From th is study t here have been foun d d ayli ght r eflectance, Y, ch romaticity coordinates (x,y) , Munsell renota.t ions, and I SCC-NBS color designations for these samples, as recommended by American W ar Stan dar d Z44-1942. As more than half of these texti le s tandards a re flu orescent, and as existing spect.rophotometers are not sui ted t o t h e evaluation of such samples, considerahle reliance has been p laced on q uantitative co lorimetri c an d p hotometric comparisons with t h e Munsell colo r standards, both by means of a chromati city-difference colorimet.er and by t he Martens p h otom eter.As a closing check, Munsell book notations of these textile standards h ave been obtained by a direct visual comparison with the color scales of t he Munsell Book of Color.
