Coloration varies somewhat between species.

Coloration is highly variable between subspecies ; it always has unmarked golden-yellow to dark brown back and wings.

Coloration is nearly the same between juveniles and adults, which is unusual among snakeheads.

Coloration varies, but the shell is usually a ruddy brown or black, fading to yellow between the scutes, and the body itself straw-yellow and brown.

Coloration of the nose is always black and the coat color is always a rich red, though a small amount of white on the chest, between the legs, or on the feet is permissible, though not preferred.

Coloration of the purple types is superficial: the edible parts are all pale yellow.

Coloration is a grayish blue-green dorsally, fading to white on the lower sides and belly.

Coloration such as this does not directly indicate that it is a severe thunderstorm, it only confirms its potential.

Coloration in New World Orioles 1.

Coloration is generally subdued yet complex ; under bright lighting, their feathers shimmer with iridescent brilliance.

( 1940 ) Adaptive Coloration in Animals.

Coloration is produced from both red pigments and yellow carotenoid pigments.

Coloration is dark blue / gray on top and lighter gray on the bottom, and the head is normally brownish.

Coloration ranges from brownish, bluish or purplish gray dorsally with lighter shades ventrally.

Coloration is typically a rich reddish brown.

Coloration superficially resembles that of some yellowjacket and hornet species.

Coloration is a golden tan to pale brown, with dark blotches on the sides and saddle-like blotches across the back.

Coloration is similar to Channa maculata, but can be distinguished by two bar-like marks on the caudal peduncle ( where the tail attaches ): in Channa maculata, the rear bar is usually complete, with pale bar-like areas before and after, while in Channa argus, the rear bar is irregular and blotched, with no pale areas around it.

Coloration is olive on the back, fading to silver with a rosy iridescence on the sides, fading to white on the belly.

Coloration of the red snapper is light red, with more intense pigment on the back.

Coloration of the red snapper is light red, with more intense pigment on the back.

Coloration varies geographically, but is generally olive green on the head blending to reddish brown in the tail.

Coloration is relatively subdued.

The extent of such interference -- which may be so slight as to be undetectable at any point where either of the stations renders a usable signal, or may be so great as to virtually destroy the service areas of both stations -- depends on many factors, among the principal ones being the distance between the stations, their respective radiated power, and, of particular significance here, the time of day.

But during nighttime hours the skywave radiations are reflected from the ionosphere, thereby creating the possibility of one station's rendering service, via skywave, at a much greater distance than it can through its groundwave signal, and at the same time vastly complicating the interference problem because of the still greater distance over which these skywave signals may cause interference to the signals of stations on the same and closely adjacent frequencies.

Indeed, the failure of home-building as a whole to respond this year to somewhat greater availability of mortgage financing, and the increasing reports of pockets of unsold homes and rising vacancy rates in apartment buildings, may also signal in part that the lush days of big backlog demand for housing are reaching an end.

Stammering or repetition of I, you, he, she, et cetera may signal ambiguity or uncertainty.

This may signal to others that the altruist is a valuable potential partner.

It may also be a signal of interactive and cooperative intentions since those not interacting further in the future gain nothing from the costly signaling.

When looking for a long-term partner more conventional altruism may be preferred which may indicate that he is also willing to share resources with her and her children while when looking for a short-term partner heroic risk-taking, which may be costly signal showing good genes, may be more preferable.

The term analog signal usually refers to electrical signals ; however, mechanical, pneumatic, hydraulic, and other systems may also convey analog signals.

In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information.

Any information may be conveyed by an analog signal ; often such a signal is a measured response to changes in physical phenomena, such as sound, light, temperature, position, or pressure.

Therefore as analog signal processing systems become more complex, they may ultimately degrade signal resolution to such an extent that their performance is surpassed by digital systems.

An analog signal may be processed directly by analog components, though some processes aren't available except in digital form.

For example, changes in signal strength may be used to specify the sounds to be reproduced by a loudspeaker, or the light intensity of television pixels.

The alphorn's exact origins remain indeterminate, and the ubiquity of horn-like signal instruments in valleys throughout Europe may indicate a long history of cross influences regarding their construction and usage.

Raymond Williams argues that there is no unique and or individual aesthetic object which can be extrapolated from the art world, but that there is a continuum of cultural forms and experience of which ordinary speech and experiences may signal as art.

As audio signals may be electronically represented in either digital or analog format, signal processing may occur in either domain.

For example, a signal may be shifted an octave up or down.
