ADA Toilet Install

Yesterday I installed a Kohler ADA height toilet in our master bathroom. I pretty much knew what to expect from installing one in the front bathroom but that didn't make the process any more enjoyable and I still ended up at Lowe's twice because I either misplaced or it didn't come with the nuts and washers for the bolts that attach the tank to the base. This was a free curb score off Craigslist and the toilet is in excellent shape except for the tank lid (model #1086929) which is cracked, but still functional. I would like to get a replacement lid eventually but first I have to figure out what color this is because it's definitely not pure white. It's more like some kind of gray. I sent a message to Kohler with the serial number so hopefully they'll be able to tell me. Update: They got back to me super quick and were able to determine the color is Ice Grey, color code 95.
