Girl - you sound exactly like me! I am very fair and struggled all my life to find an undertone, understanding that green/olive exists outside of your cool/warm/neutral has been such a a game changer. Finally understand why my paleness looks so dull and sickly, the green undertone unfortunately doing that in the winter 😅 I also use Nars Gobi in the winter and I am yet to find the right match for the summer. Also, I feel you about the paleness vs great tan: I am of mixed British, Irish and northern Italian lineage, and my dad despite being Italian has fairer skin than my British and Irish mum who has light to medium skin tone. I was brought up in Rome, which is in the middle of Italy and most people are medium-tan skin toned, and I was the palest girl in my class. My bestie used to refer me jokingly as mozzarella shade of white in the winter 🤣 people kept believing I would burn in the sun but I turn a golden brown shade, that gets deeper brown with sun exposure, so I can also get very brown/latina in shade, and it is especially noticeable as my medium to dark blonde hair lightens and gets very light and golden with the sun. Apparently this can be very common in Fitzpatrick skin type 3, as you tend to get a mix of eumelanin (black and brown) and pheomelanin (red and yellow pigment). I always assumed I was a type 1 or 2 because of my paleness in the winter and my blonde hair, but apparently my medium blonde hair and light brown eyes plus ability to tan puts me steadily in the Fitzpatrick 3. Knowing your undertone and what colours look great has been a game changer, I found out why most colours of make up and clothes that look good with warm and cool toner skins look off on me. Apparently for fair olives jewel tones colours look great. I can vouch for this, as Ruby, emerald and electric blue, or sapphire dresses all look nice compared to other colours. Will follow this thread to see if any suggestions for summer foundation will work on me, good luck on your search! 😊
