Effects of plasma-activated solution (PAS) on the colour and structure of metmyoglobin (metMb) and oxymyoglobin (oxyMb) were investigated and the relationship between discolouration and structure changes was clarified for the first time. Results showed that the colour of PAS-treated metMb faded first, followed by green discolouration, while PAS-treated oxyMb turned from bright red to reddish-brown and then towards green in the end. It was due to the accumulation of HO, nitrite and nitrate in PAS with prolonging plasma treatment times. Read More

Transcriptional analysis reveals key insights into seasonal induced anthocyanin degradation and leaf color transition in purple tea (Camellia sinensis (L.) O. Kuntze).

Sci Rep 2021 01 13;11(1):1244. Epub 2021 Jan 13.

Department of Biotechnology, CSIR-Institute of Himalayan Bioresource Technology, P.O. Box No. 6, Palampur, HP, 176061, India.

Purple-tea, an anthocyanin rich cultivar has recently gained popularity due to its health benefits and captivating leaf appearance. However, the sustainability of purple pigmentation and anthocyanin content during production period is hampered by seasonal variation. To understand seasonal dependent anthocyanin pigmentation in purple tea, global transcriptional and anthocyanin profiling was carried out in tea shoots with two leaves and a bud harvested during in early (reddish purple: S1_RP), main (dark gray purple: S2_GP) and backend flush (moderately olive green: S3_G) seasons.

Color Compensation in Anomalous Trichromats Assessed with fMRI.

Curr Biol 2021 03 15;31(5):936-942.e4. Epub 2020 Dec 15.

Department of Psychology, University of Nevada, Reno, 1664 N. Virginia Street, Reno, NV 89557, USA.

Anomalous trichromacy is a common form of congenital color deficiency resulting from a genetic alteration in the photopigments of the eye's light receptors. The changes reduce sensitivity to reddish and greenish hues, yet previous work suggests that these observers may experience the world to be more colorful than their altered receptor sensitivities would predict, potentially indicating an amplification of post-receptoral signals. However, past evidence suggesting such a gain adjustment rests on subjective measures of color appearance or salience. Read More

Large enhancement of simultaneous color contrast by white flanking contours.

Sci Rep 2020 Nov 18;10(1):20136. Epub 2020 Nov 18.

Department of Computer Science and Engineering, Toyohashi University of Technology, Toyohashi, Aichi, 441-8580, Japan.

Simultaneous color contrast and assimilation are mutually opposing effects on color appearance, and their magnitude depends on spatial context. The Monnier-Shevell illusion induces a large color shift by a synergy of simultaneous assimilation and contrast using the alternating color of proximal and distant surrounds. The illusion induces a prominent effect along the blue-yellow color axis, but a subtle effect along the orthogonal color axis. Read More

Color Space Geometry Uncovered with Magnetoencephalography.

Curr Biol 2021 02 16;31(3):515-526.e5. Epub 2020 Nov 16.

Laboratory of Sensorimotor Research, National Eye Institute, Building 49, NIH Main Campus, Bethesda, MD 20892, USA; National Institute of Mental Health, Bethesda, MD 20892, USA. Electronic address:

The geometry that describes the relationship among colors, and the neural mechanisms that support color vision, are unsettled. Here, we use multivariate analyses of measurements of brain activity obtained with magnetoencephalography to reverse-engineer a geometry of the neural representation of color space. The analyses depend upon determining similarity relationships among the spatial patterns of neural responses to different colors and assessing how these relationships change in time. Read More

Department of Agricultural Biotechnology and Research Institute of Agriculture and Life Sciences, Seoul National University, Seoul 08826, Korea.

Synthetic nitrite imparts a reddish-pink color to meat and a distinct flavor to meat products, delays lipid oxidation, and inhibits microbial growth and pathogens. However, excessive intake of nitrite might result in the production of carcinogenic nitrosamine, which might increase the risk of cancer in humans. Therefore, we aimed to find an alternative natural colorant for pork sausages. Read More
