Illuminant
metamerism is when two samples having different spectral characteristics match when viewed by a normal observer under a given illuminant, but no longer match when viewed by the same observer using the same illuminating and viewing geometry but with a different illuminant.
4 a) and b) presents colour quality indices for five WLL based on the second set of LED metameric to reference DAY, and A sources respectively, as a function of the relative LED flux intensity, which is defined as ratio (B-GB)/(B+GB), where B and GB are the relative flux intensity of blue and blue-green LED respectively, as the
metamerism of WLL is mainly achieved by varying the flux intensities of the blue and blue-green LED.
Metamerism, the capacity of some colors to present the same color appearance in some scenes and conditions of illumination, can raise an epistemological problem.
It has to do with
metamerism, which is a phenomenon that occurs when colors change when viewed under different light sources.
Sample MHS 010130.3--possible penaeid shrimp, LACMIP Hypotype 6945--antennae very long, curving abdomen exhibiting some
metamerism, pleurae vague (Figure 3)
When it comes to reproducing quality digital photos, Epson more than a year ago solved one of the most difficult technical challenges--high-quality black and white images without the effects of
metamerism (a greenish effect on black and white photography).
Because standard display technology attempts to match all colors by mixing only red, green, and blue on a CRT or LCD monitor, there can be significant viewer
metamerism when the monitor color is compared to real dyed or pigmented samples.
Metamerism, heterochrony, and inflorescence morphology of the Pithecellobium complex (Leguminosae: Mimosoideae: Ingeae).
It's
metamerism, a color match between two materials in which colors are identical under some lighting conditions but not under others.
It may well be that after, say, the invention of multicellularity, or the invention of
metamerism, evolution was never the same again.
Many sample pairs have the capacity under one illuminant to appear identical to one another, when under another illuminant they exhibit distinct color differences (
metamerism).
