Color tool
The Color tool searches various KEGG objects, including genes, KOs, EC numbers, metabolites and drugs, against KEGG pathway maps. Found objects may be marked in any combination of background and foreground colors.

Usage
Query data format
Two-column dataset (space or tab separated) with KEGG identifiers in the first column and color specification in the second column, which takes the form of "bgcolor,fgcolor" (no spacing) where bgcolor and fgcolor may be specified by color name such as red or hex rgb such as #ff0000. When multiple colors are specified to the same box (gene product), split coloring is performed (see
Map coloring GUI). For lines (gene products in the global and overview maps) and circles (chemical substances) the first color specification is used.

Use of gene symbols
The use of gene symbols (in the Gene name field of GENES entry) as aliases is no longer supported, because many-to-many relationships may result in erroneous links to KEGG identifiers.
As an exception, the official symbols for hsa (Homo sapiens) can be used as primary identifiers, which are automatically converted to KEGG identifiers by using the one-to-one correspondence between NCBI Gene IDs and HGNC symbols. Note, however, that the correspondence is updated every three months of RefSeq releases. It is highly recommended to always use KEGG hsa gene identifiers.
