The colon from the splenic flexure to upper rectum drain to the inferior mesenteric lymph nodes (FA2020 p97).
You can remember this because this is a part of the hindgut which is supplied by the inferior mesenteric artery.
NOTE: The anal canal has different lymphatic drainage that is worth noting (FA2020 p366) - above the pectinate line and lower rectum drains to the internal iliac lymph nodes and below the pectinate line drains to the superficial inguinal lymph nodes.
