Plus, early TH9 has crazy high elixer requirements, so you won't even be able to dump elixer effectively until much later in the town hall.
So, with that in mind, my opinions:
I got full pink in TH7 because resources were flowing everywhere, and I did the pink walls early in the TH, while I was upgrading everything I could with elixer. While I saved up elixer, I used walls as a place to essentially hide whatever gold I acquired. This was before the elixer->wall update.
In TH8, before the elixer->wall update, I got full purples. Again, I had a lot of gold, and I did them early, while I was saving for high elixer upgrades. I found that if I had 2 million of both resources, I got raided by TH9 Giant+Healer+Heroes+Spells super often, and it was frustrating. However, if I only had 2m+ elixer, and virtually zero gold, I got hit by big attacks much less frequently. By the time I finished up with purple walls, the elixer->wall change happened, and I had just started my upgrade to TH9 (max defense TH8 except Teslas, BK at level 5, lab complete except for DE Troops and Pekka (not upgrading my pekkas at TH8 is about my only regret)).
I did the same thing again - used skull walls simply as a place to hide my gold while I saved up the 6 million elixer needed for each troop upgrade. Any gold in excess of that went to the new defenses and new walls and such. Now, I'm in mid-ish TH9 (both heroes ~10, max Xbows, about 9million elixer in buildings left to do). I'm currently working on teslas, so it's giving me a good amount of time to work on walls at the same time. I upgrade 2 teslas and 2 heroes at a time, leaving my 5th builder to resource dump into walls. Again, same thing as TH8. If I show 200k+ elixer/gold + 1500+ DE, I get smashed by TH10s pretty frequently. If I show virtually zero elixer, I get raided much less frequently.
I wouldn't spend idle builder days maxing walls at any given TH. Just use them to hide and dump your resources, and they will naturally get maxed eventually. You have a lot of lab time in TH8, and a lot of builder days in TH9, that allows plenty of time to catch up with walls.
For me, I'm shooting for either level 15 heroes or level 20 heroes before I hit TH10, as I will have a lot of demands on my builder's time, so I plan on taking a break from upgrading heroes for a little while, and I'll use them to raid while I get my barch up to level 7. Once my barch is level 7, I can start back up on upgrading my heroes.
