Out of three perceptual characteristics of the colour of any substance, the hue depends mostly on the spectral properties of a substance, while the brightness and saturation depend also on the concentration of a substance and its thickness. Here, we report that evident change of the hue of the colour (i.e., from green to red) is due to a change in concentration or the thickness of a layer in some exceptional substances such as pumpkin seed oil or an aqueous solution of bromophenol blue. In some… Expand
Dichromatism causes color variations in leaves and spices
TLDR
Dichromatism in leaves caused uniform negative correlation between lightness and hue in any plant species examined, and this correlation was successfully explained by calculation with a normalized RGB color matching function. Expand

TLDR
It is shown that dichromatism is a common property of many substances and materials, and a method for its quantification is introduced. Expand
Histolocalisation of the oil and pigments in the pumpkin seed
TLDR
This study localised the oil to the small lipid droplets in the cotyledon cells by Rhodamine 6G lipophilic stain and localised protochlorophyll to chlorenchyma by microscopic fluorimetry. Expand
Colour analysis of potential natural colourant from Ixora siamensis and Melastoma malabathricum
Abstract Anthocyanins are an important group of natural pigments that are responsible for many colours in plants. The variation in colour, depending on the pH, makes them a unique source of naturalExpand
Colour phenomena and selective absorption: the role of thickness of absorbing medium 1
This experiment (ADT: absorption with different thicknesses) is focused on selective absorption by solutions or other media constituted of successive transparent layers. It is designed in order toExpand
Pumpkin (Cucurbita pepo L.) Seed Oil
TLDR
P pumpkin seed oil (PSO) is highly unsaturated oil containing predominantly oleic and linoleic fatty acids and this feature makes PSO well suited for improving the food nutritive value. Expand
Phenolic compounds and some quality parameters of pumpkin seed oil
Pumpkin seed oil has become a recognized source of phenolic compounds. The main aim of this paper was to evaluate the concentration of phenolic compounds and their extraction from pumpkin seed oil.Expand
Reverse dichromatism in gem andalusite related to total pleochroism of the Fe2+-Ti4+ IVCT.
We document a dichromatism effect in gem andalusite that shifts from light brownish pink at low thickness to medium green at high thickness. This is roughly reverse to that usually observed in otherExpand
Spectral Analysis of Catalytic Oxidation and Degradation of Bromophenol Blue at Low pH with Potassium Dichromate
Abstract This research investigated the efficacy of potassium dichromate (K2Cr2O7), ultraviolet (UV) solar irradiation and UV in combination with two diprotic acid i-e sulphuric and oxalic acid (UVExpand
Nutritional Evaluation, Physico-Chemical Characteristics, Fatty Acid Composition and Mineral Contents of Some Vegetable Seed and Oils
Abstract Some physico-chemical characteristics, fatty acids and mineral contents of pumpkin, sweet pumpkin, melon, watermelon, paprika, tomato and cucumber seeds were determined. All seeds containedExpand

TLDR
Among cone fundamentals that might be chosen, a set derived and published by Stockman, MacLeod, and Johnson is favored here, and some of the advantages for displaying visual data in a system based on these fundamentals are illustrated. Expand
