We propose a simple five-layer structure for creating red structural color, which has high color purity and brightness. The design is based on the superposition of silver substrate multilayer silicon material. Absorption at shorter wavelengths effectively guaranteed, reflection longer well enhanced. peak reflectivity 91% colorimetric 0.9. Moreover, designed displays angle-invariant performance ...

This article deals with a red-scale measurement system which can be applied to Wire Rod Production Line in POSCO (Pohang Iron and Steel Company). A red-scale is a type of oxidized Fe coated on the surface of wire rod and as the name means it has red color. The main cause of red-scale is an improper control of cooling process after final milling stage. To control the cooling process we need to m...

Color does not normally indicate a problem. Whether or not the gonads are melanistic is unremarkable. Occasionally a bird will have one testicle that is melanistic and one that is white. Sometimes the testes appear pink in color due to increased vascularity. Superficial blood vessels can be large and appear as flat red lines or streaks. This is normal. Rarely testicles can become inflamed and a...

Several studies document rudimentary color vision under dim illumination. Here, hue perceptions of paper color samples were determined for a wide range of light levels, including very low light levels where rods alone mediate vision. The appearances of 24 paper color samples from the OSA Uniform Color Scales were gauged under successively dimmer illuminations from 10-0.0003 Lux. Triads of sampl...

Color is a ubiquitous perceptual experience, yet little scientific information about the influence of color on affect, cognition, and behavior is available. Accordingly, we have developed a general model of color and psychological functioning, which we present in this article. We also describe a hypothesis derived from this model regarding the influence of red in achievement contexts. In additi...

Regional cerebral blood flow, an index of local neuronal activity, was measured using positron emission tomography (PET) during the performance of the classic Stroop color/word task in eight healthy right-handed subjects. In the first condition of this paradigm, subjects name the color of the words presented on a video monitor. All the words are the color names congruent to the color presented ...

Mulches bring several benefits to lettuce cultivation.A study on the lettuce ‘Red Rapids’ has been conducted to determine the influence of the different colored plastic mulch on its growth. The experiment consisted of five color treatments as follows; treatment 1- metallic silver (control), treatment 2- red, treatment 3- orange, treatment 4- yellow and treatment 5-green. Results showed that the...

The aim of the present study was to evaluate the changes in radiofrequency ultrasound local estimator (RULES) images with different instrument settings. An Esaote Technos MPX Color Doppler Ultrasound Machine and RULES were used to capture images of a gallbladder model. The percentages of various colored areas (color filling rates) within the area of interest were calculated using different inst...

color had a special role in the human life. today psychologists use colors to do researches and recognition of people's mental characteristics. luscher's color test is further one of many well known tests. in the literature world a poet shows his way of thinking by using some special words. this research uses the luscher color test and measures the person's psychophysical state based on samih a...

CMYK vs. RGB Color images are printed on paper by separating their colors into four component parts: cyan, magenta, yellow, and black ( CMYK ). Each of the colors in an image is created by assigning a percentage from 0–100 to each of the aforementioned colors (for example, a red color could be created from 0% cyan, 100% yellow, 100% magenta, and 0% black). The color image is then printed on a m...
