The Great Circle Mapper's Blue Marble maps use the Next Generation imagery.
Valid colors include those offered for any of the color options in the Map Controls. In addition, colors can be specified using hexadecimal colors using a syntax like that used by CSS. For example, c:#ff0000 is the same as c:red.
The length of a URL does limit the complexity of maps which can be requested, however. Internet Explorer has a maximum URL length of 2,083 characters which is probably the most restrictive limit. Most other browers are less restrictive, in which case the limit becomes the length of a request line accepted by the Apache HTTP Server software. This limit is less than 8,190 bytes.
Work is underway to allow map definitions to be saved on the Great Circle Mapper web site which will allow more complex maps without exceeding HTTP's limits on URL lengths. (There is not yet a target date for when this work will be completed.)
