Stick w/the bright white,.. over time it will match better.
on a side note I had two small tears in my vinyl, and those 'vinyl repair kits' absolutely suck! ....made it look worse!! So, I got a tube of high quality silicone (like outdoor window silicone in white so i could tint) bought some Testers enamels in different colors, mixed till I was happy with the color, then applied,...still looks great two yrs later, barely noticeable.
Looks good!
I am in the process of doing all of mine now. I went with the sea ray champagne. It is an off white/light tan.
sofar I got 20 of 26 cushions/ vinal pads done. Its taken abit, but definitely gonna be worth it.
hopefully they will last 2-3 years. Will be very careful when all done
