Go to Media Generator tab, solid color, pick white. In the Color sliders set R 255 G 70 B 127 A 255. If not exactly what you want play with the sliders a bit. Once you get close NOW drop in the Color Corrector filter. Move the mid and high wheels to get what you want while adjusting Gamma and Gain. Took me longer to write this.
SCAN in the colour-way OR swatch you like. Save as a PNG bring onto T/L, use the eyedropper to sample the colour .. voila! The colour numbers appear; the sample appears; you can copy and paste this anywhere yer want it!
