I currently wear Gabor sandy blonde SS (14/24SS) but the base is more of a strawberry blonde than the color suggests. Are either Misty Sunrise or Velvet Cream close to the Gabor color?
The closest match to your favorite shade, Gabor's GL14/22SS: Shaded Sandy Blonde is going to be Misty Sunrise. Heather has a great in-depth color spotlight really breaking down and explaining this shade: https://www.youtube.com/watch?v=vLmq22AmwAk
Mimosa HL is going to be a little bit darker than what I feel you're looking for, but a great rooted option! You can watch Heather's in-depth color spotlight on this shade here: https://www.youtube.com/watch?v=erV8xZJg6hQ
You also may like Velvet Cream, it has a base of a light, natural auburn with blended blonde highlights throughout. You see Heather go into more detail on this color here: https://www.youtube.com/watch?v=aOvXlYsGtXo
