Here, it works too hard, pounding on the obvious, waxing purple where it strains for grand significance.
Encounter, a 1960s-vintage restaurant, was the most obvious, a purple-windowed flying saucer standing atop a pillar right outside Terminal 2. The dining room was a modern take on space-age chic — undulating blobs of color on the ceiling, a lava lamp on the bar and hardly a right angle in sight — with 1980s hits like "Smooth Operator" playing on the sound system.
In presence of Fe3 +, sensor L displayed strong colorimetric response as amaranth to rose pink and significant fluorescence enhancement and chromogenic change, which served as a naked-eye indicator by an obvious color change from purple to red.
Flower: 8--10 mm, +- narrowed above ovary; perianth parts erect, lance-linear, long-tapered, pink to purple, midveins obvious, +- green; stamens exserted, bumpy or warty near base; ovary crests 6, obscure, central.
Admittedly, I was dubious about the "recognition" of these and other lesser wounds; I felt that in a way they subverted the obvious intent of the Purple Heart — honoring soldiers who have been seriously hurt.
Various degrees of purple color were obvious among different rice accessions.
Moreover, it can be used as a "naked eye" indicator for Cu2+ with an obvious color change from colorless to purple upon the addition of Cu2+.
The recognition of Cu2+ by PAM-PBI showed an obvious color change from rose red to purple in aqueous solution, while the sensing of F− gave a marked color change from rose red to light green in THF.
The obvious quenching of fluorescence and red-to-purple color change shows P1 can act as the great promise sensor for the detection of fluoride ion.
Flower: (6 8--12 mm; perianth parts lanceolate to ovate, entire, dark red-purple to white; ovary crests 6 8--12ous, dentate to deeply cut.
