For Yellow, I used PY:153 Indian Yellow from Utrecht and  PY:153 Gamboge Hue from Cotman. They seemed identical to me.
My Magenta PR:122 and Cyan PB:15.3 were both from MaimeriBlu,
called 473 Violetto Verzino and 400 Blu Primario, respectively.
The chilis were on a galvanized tin sheet. I tried later to put that in but ruined the painting. I'm not a fast enough painter or I would have tried to capture the beautiful scene before me as the sun went down and the orange light came streaming across at a low angle from the left, making the peppers simply radiant. I will hang that in the virtual gallery of my mind.
