i am attempting to capture a color, i'll call it PMS 490, and how it is affected by its environment during a sunny and during an overcast day. i want to see exactly how 490 looks when affected by those elements. i do not want the camera to alter the color or the monitor to alter the color or the printer to alter the color. but i do want to see how the direct sun and indirect sun (sunny and overcast) affects that solid color. my thought is to purchase the ColorChecker Passport by Xrite so i can dial back in a profile that was recorded at the very moment i shot the PMS 490. that way i can see, without any other influences, how the sun/lack of affected that solid color. what are your thoughts on the most scientific way to go about achieving this and arriving a a true color as it is affected by the sun and overcast?
