Common Spot Colours

Commonly requested Pantone colours for NZ label printing. Spot inks give you colours that CMYK cannot reproduce — metallics, neons, and ultra-vivid hues.

Pantone	CMYK Build	Hex	Common Use	Note
186 C	0/100/81/4	#C8102E	Brand reds, sports teams	Process build is close but spot gives punchier red

021 C	0/53/100/0	#FE5000	Bright orange accents	Highly saturated; process build looks duller
123 C	0/24/94/0	#FFC72C	Gold-yellow, honey labels	Good CMYK match; spot gives richer gold
