thank you for your comments, guys.
Yeah, I took the side stripes not really into consideration yet. But it is always the overall impression which counts.
Like my wife says...color matching is most important...all of them.
You guys said, that "white-ish" color is not matching and you are right.
so a more adapted design...trying a different side liner color in the middle segment
...and omg...the sand color lightens up...so even that needs to be played with to get the perfect "sand color impression"
... it still needs a few more tweaks to figure out the perfect harmony
