The standard KOH wet mount lacks a color contrast. Various contrast dyes are available. Parker ink is one which has been extensively used, however in recent times the stain no longer provides a suitable color contrast. Two other dyes that are available are Chicago blue and chlorazole black.<\/jats:p><jats:p><jats:bold>Methods\u2002<\/jats:bold> 100 samples of skin or nails were prospectively examined using Chicago blue, chlorazole black, and Parker ink\u2010KOH stains. The samples were also cultured, with culture being the diagnostic gold standard.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold> The sensitivities and specificities of the Chicago blue, chlorazole black and Parker ink stains were 78% &amp; 96%; 63% &amp; 97%; and 48% and 96%, respectively.<\/jats:p><jats:p><jats:bold>Conclusion\u2002<\/jats:bold> The Chicago blue\u2010KOH stain provides a good color contrast and is a suitable replacement for the Parker ink\u2010KOH stain.
