Well... Bill said it right...it's a personal choice. But my choice would be this (given the selections you offered.)
"If it was me.........as the old saying goes" I would go with:
Two tone seats using Biscuit for the seat tops and lower back section of the backs and the Cream color for the lower perimeter of the seats (skirt) and tops of the backs.
Consider that these colors would complement each other and equally important consider texture differences too.
This color and texture selection would do well with the Sand colored carpet.
Think about the early 1947- through early 49 GMC interior truck cab color that is a brownish/metallic/beige/gold color. PPG makes the highest quality paint by using their their top end brand - highly suggest this - a real nice paint for this and your Suburban. The color is the same used on the 1986 Corvette known as Medium Brown Metallic. I have the color codes for PPG and the Nason brand paint lines for this color.
FYI: I did a little experiment comparing the two PPG brands and the Nason brand medium brown metallic . What you pay is what you will get and achieve in color, depth and overall look. The high end brand of PPG mixes about 12-13 color hues and their lower quality brand mixes about 6-7 hues. There is a difference. The Nason brand fits right in between these two PPG lines. And, the price range for each matches up to each other too...the Nason brand being right in the middle price range ...and the quality of depth and color quality compares equally to the price range.
Just my 2 cents to thnk about. Having another color inside is a nice touch and adds more interest to the vehicle.
...I'll locate the color codes when I can go back to the shop. HTH and probably muddies the water for you too! Aren't you glad you asked?
I like your color choices for the carpet and seats. tom
p.s.
If you have a hard time finding this color in the PPG line in the UK...let me know and I can order and ship some to you from the States. I would be happy to do this...and really think these color combinations would look classy and real nice....not forced but understated. or I can hand deliver it for airplane and lodging tickets!!
