My use of the darker almost red orange is so it is more versatile in my designs like the tomato and the earth and the inside of the mouth.
#26 is representative of a mouth consuming something Uber and speaking the word yummy. The white squares are teeth as well as just design elements but the thin lines can be removed to just show the bottom edge of the 4 teeth since they aren't necessarily needed to get that idea across.
#27 and #28 are supposed to represent vegetation in the green and earth in the dark orange, with a sun shining over the land which gives life to your livelihood it leans a little more towards a produce label logo...
