Table 1. Relationship between visual cues and stimulus temperatures.

Cue Colour	R	G	B	Stimulus Temperature
Pink	225	0	102	32°C
Orange	247	150	70	41°C
Purple	128	100	162	45°C
Blue	75	172	198	32 or 41 or 45°C

Note: Each block comprised 24 stimuli, in which each target temperature was delivered eight times in pseudorandomised order; 50% preceded by their partnered unambiguous cue, while the remaining 50% were preceded by the ambiguous cue. The RGB values refer to the additive colour model in which red, green, and blue are added together to produce a broad array of colours.
