| match | 1. A person or thing equal or similar to another; one able to mate or cope with another; an equal; a mate. "Government . . . Makes an innocent man, though of the lowest rank, a match for the mightiest of his fellow subjects." (Addison) 2.

Suitable combination or bringing together; that which corresponds or harmonizes with something else; as, the carpet and curtains are a match. 7. A perforated board, block of plaster, hardened sand, etc, in which a pattern is partly imbedded when a mold is made, for giving shape to the surfaces of separation between the parts of the mold. Match boarding, a cogwheel of suitable pitch to work with another wheel; specifically, one of a pair of cogwheels of equal size. Origin: OE. Macche, AS. Gemaecca; akin to gemaca, and to OS. Gimako, OHG. Gimah fitting, suitable, convenient, Icel. Mark suitable, maki mate, Sw. Make, Dan. Mage; all from the root of E. Make, v. See Make mate, and Make, and cf. Mate an associate. Anything used for catching and retaining or communicating fire, made of some substance which takes fire readily, or remains burning some time; especially, a small strip or splint of wood dipped at one end in a substance which can be easily ignited by friction, as a preparation of phosphorus or chlorate of potassium. Match box, a box for holding matches. Match tub, a tub with a perforated cover for holding slow matches for firing cannon, esp. On board ship. The tub contains a little water in the bottom, for extinguishing sparks from the lighted matches. Quick match, threads of cotton or cotton wick soaked in a solution of gunpowder mixed with gum arabic and boiling water and afterwards strewed over with mealed powder. It burns at the rate of one yard in thirteen seconds, and is used as priming for heavy mortars, fireworks, etc. Slow match, slightly twisted hempen rope soaked in a solution of limewater and saltpeter or washed in a lye of water and wood ashes. It burns at the rate of four or five inches an hour, and is used for firing cannon, fireworks, etc. Origin: OE. Macche, F. Meche, F. Meche, fr. L. Myxa a lamp nozzle, Gr. Mucus, nostril, a lamp nozzle. Cf. Mucus. Source: Websters Dictionary (01 Mar 1998) |

| blue white colour selection | <molecular biology, procedure> Method for identifying bacterial clones containing plasmids with inserts. Many modern vectors have their polycloning site within a part of the LacZ gene encoding _ galactosidase, which provides _ complementation in an appropriate mutant E. Coli strain. This means that a re ligated (empty) vector will produce blue colonies when grown on plates containing IPTG and X gal, but colonies with a substantial insert in their plasmid's polycloning site are unable to produce functional _ galactosidase and so produce white colonies.

| Reuss' colour tables | An obsolete charts in which coloured letters are printed on coloured backgrounds in such combination that some of them are invisible to a person with deficient colour vision. Synonym: Stilling colour tables. (05 Mar 2000) |
| colour | 1. That aspect of the appearance of objects and light sources that may be specified as to hue, lightness (brightness), and saturation. 2. That portion of the visible (370-760 nm) electromagnetic spectrum specified as to wavelength, luminosity, and purity. Origin: L. (05 Mar 2000) |
| colour aberration | When using white light through a lens system, it is inevitable that different wave lengths (colours) are brought to a focus at slightly different points. As a consequence, there are chromatic aberations in the image, good microscope objectives are therefore corrected for this at two wave lengths (achromats) or at three wave lengths (apochromats), as well as for spherical aberration. (18 Nov 1997) |
| colour agnosia | The inability to name or identify specific colours by sight; caused by lesions of the dominant occipital and temporal lobes. (05 Mar 2000) |
| colour blindness | A sex-linked inherited condition where there is an inability to distinguish colours. Very few women are colour blind, but up to 10% of all men have some degree of colour blindness. The most common for is red-green colour blindness. The second most common is blue-yellow. Inheritance: sex-linked (X chromosome). (27 Sep 1997) |
| colour constancy | Unchanging perception of the colour of an object despite changes in lighting or viewing conditions. (05 Mar 2000) |
| colour-contrast microscope | <instrument> A type of microscope in which the condenser stop is of one colour and the annulus is a complement of it so that unstained objects are observed in one colour on a field of the other. (05 Mar 2000) |
| Colour Index | A publication concerned with the chemistry of dyes, with each listed dye identified by a five-digit Colour Index number, e.g., methylene blue is Colour Index 52015. (05 Mar 2000) |
| colour perception | The visual awareness of any particular hue or achromatic colour. (12 Dec 1998) |
| colour radical | The part of a visibly coloured molecule responsible for light absorption over a range of wavelengths thus giving rise to the colour. By extension the term may be applied to UV or IR absorbing parts of molecules. Do not confuse with chromatophores. (18 Nov 1997) |
| colour scotoma | An area of depressed colour vision in the visual field. (05 Mar 2000) |
| colour sense | The ability to perceive variations in hue, luminosity, and saturation of light. (05 Mar 2000) |
| colour solid | A schematic arrangement of colour in space, the attributes of hue, saturation, and brightness being represented by cylindrical coordinates. (05 Mar 2000) |
