abstract rainbow wave line background for template design

>For other uses, see Rainbow (disambiguation). A rainbow is an optical and meteorological phenomenon that causes a nearly continuous spectrum of light to appear in the sky when the sun shines onto falling rain. It is a multicoloured arc with red on the outside and violet on the inside. The full sequence of colours is most commonly cited as red, orange, yellow, green, blue, indigo, and violet, though it is important to note that this is an inconsistent list; all primary and secondary colours are present in some form, but only one tertiary. It is commonly thought that indigo was included due to the different religious connotations of the numbers six and seven at the time of Isaac Newton's work on light, despite its lack of scientific significance and the poor ability of humans to distinguish colours in the blue portion of the visual spectrum.

[emplate is some form of device to provide a separation of form or structure from content.In publishing for example, a template may be a predefined layout to give you an idea what to write where with boxes and lines; a single-page newsletter template (for instance), might have a few columns, space for a picture and gaps for the headline and name of the newsletter.Templates can be used by humans or by automated systems; many web-based software packages now use a templating system to separate the logic of the program from the displayed formatting. Typically, these templates will include variables (often denoted {VARIABLE} ), and possibly a few logical operators to allow better adaptability of the template. Examples of template engines are Cheetah, Smarty and XSL Transformations. See more at Wikipedia.org...]
