The objective of this project is to establish a practical application of the concept of Color Universal Design (CUD), the design that is recognizable to all color vision types. In our research, we looked for a clearly distinguishable combination of hues of four colors – black, red, green, and blue – which are frequently used in these circumstances. Red-green confusion people do not confuse all ...

Physiological studies of color have uncovered many puzzles. Here are four puzzles. First, neurons in the lateral geniculate nucleus (LGN; Fig. 1) are strongly color opponent, but the opponency does not correspond to Hering's fundamental opponent-color pairs (red–green, blue–yellow) (Webster et al., 2000); moreover, the color-tuning of the population of LGN cells is not balanced across color spa...

although wild safflower (c.oxyacantha, 2n=24) has not been studied to a very large extent, yet it is believed that it can be used as an important source of biotic and abiotic stress resistance genes for improvement of cultivated safflower (c.tinctorius l., 2n=2x=24). in this study, the crossability between these two (cultivated and wild safflower) species was evaluated as based upon morphology ...

We present measurements of the color and luminosity dependence of galaxy clustering at z ∼ 1 in the DEEP2 Galaxy Redshift Survey. Using volume-limited subsamples in bins of both color and luminosity, we find that: 1) The clustering dependence is much stronger with color than with luminosity and is as strong with color at z ∼ 1 as is found locally. We find no dependence of the clustering amplitu...

We use a sample of 69726 galaxies from the SDSS to study the variation of the bimodal color-magnitude (CM) distribution with environment. Dividing the galaxy population by environment (Σ5) and luminosity (−23 < Mr < −17), the u− r color functions are modeled using double-Gaussian functions. This enables a deconvolution of the CM distributions into two populations: red and blue sequences. The ch...

The first step in communicating color is to name it. The second step is color semiotics. The third step is introducing structure in the set of colors. In color education at all levels, this structure often takes the form of formulæ, like red + green = yellow, or turquoise + red = black. In recent times, Johannes Itten’s color theory and its associated color wheel have been very influential, mos...
