Consider High Tide for ramp and/or with spells that can untap your Islands Turnabout, Frantic Search, Snap? Just Tide + Turnabout + you control 4 Islands could give you 10 mana turn 4. Mystic Sanctuary is a fantasic land that's an Island. Castle Vantress isn't an Island, but it's a good land for instant repeatable scry.

Consider Thought Vessel and/or Decanter of Endless Water? Mana rocks for ramp that can also potentially give you no max hand size before you control Nezahal. Reliquary Tower is a land for no max hand size.

Consider Forensic Researcher, Kelpie Guide, etc.? They can untap a land or a land that can make more than 1 mana Arid Archway, Guildless Commons even the same turn the land ETB. They can also untap a mana rock or even better a mana rock that can make more than 1 mana Sol Ring, Worn Powerstone, Palladium Myr, Thran Dynamo, Hedron Archive, Gilded Lotus, etc. They can also untap Nezahal to be a blocker.

A spell advantage blue has are instants that let you look at top X cards of your library and put one or more of any of them into our hand (any card(s) into hand is the advantage). Consider Impulse, Memory Deluge, Dig Through Time, Supreme Will, Thassa's Intervention, etc.? When you're casting instants on opponents' turns then Wavebreak Hippocamp is repeatable card draw. Being a 3 drop you can more safely play it and leave up mana for instant opponent interaction.

In blue, the Urza's Block hugely skew land untapping, and that block is widely considered to be an overpowered mistake, especially for blue. Urza's Saga and Urza's Legacy alone have ten cards that allow land-specific untapping, more than half of all the blue cards that allow untapping lands without untapping all permanents. They'll be included for the sake of completion, but I wouldn't take them as any sort of precedent. Pioneer legality is just five cards, with one of them being Standard-legal. Blue is the undisputed king of untapping permanents in general, but doesn't have any special focus on lands.

There's 44 mono-blue cards that can untap lands in some capacity, with 20 of them being more specific than untapping permanents in general. If Urza's Block is taken out, then there are 34 blue cards that untap lands, with just nine of them having any sort of restriction.

So in final summary, I see green land untapping increasing in recent years, and blue permanent untapping actually falling off slightly. There were 18 blue untap cards in the 12 years of the modern border, and nine cards so far in the nine years of the 2015 border. Discounting Urza's Block, there are slightly more green cards that can untap lands than blue cards, and many more green cards that untap lands than blue cards printed in the last ten years.

If I missed anything in this breakdown, please let me know. But I think the cards are there to support my initial position. Both green and blue are primary in untapping lands, if lands are counted as permanents, and blue is secondary in untapping lands specifically. Mark Rosewater's answer is is at best incomplete and missing nuance, and at worst totally wrong.

Keeping the above because it took me a long time write and I don't want to undo the effort.

In response to wallisface, percentage of cards with a given effect doesn't matter to primacy of color.

• Primary – This is the color (or colors) the ability is seen in most. That means it shows up in the highest volume and usually at the lowest rarity that the type of effects get used at. The primary color will almost always get this effect in a set if it's an ability we do every set. It also tends to be the color that most often pushes the power level, if it's an effect we push the power level on. There's a wide range on what primary means, because different types of effects exist at different levels. A card secondary in flying can show up way more than a card primary in taking extra turns, for instance, because we have so many more flying cards than extra-turn cards.

• I want to stress one more time that primary, secondary, and tertiary are relative to how often an effect is used. Things that are secondary in a color, for example, may be far more prevalent in that color than things that are primary if the items in question occur at a higher frequency.

For example, MaRoo has repeatedly stated that red is primary in extra combat cards, with white as a contender for secondary.

There are only 36 cards that grant an additional comabt. If primacy was considered as a proportion of cards that grant additional combats was considered only as a proportion of total cards of that color, I don't think any color would be considered primary.

So while there might be fewer cards that untap lands in green as a proportion of total green cards in recent years, that's not a relevant measure to color primacy. The relevant measure is how often cards that untap lands show up in green compared to other colors, which I think is demonstrated by the above lists that green has more land untap effects than any other color, with blue being nearly equivalent. That, according to MaRo's definition, means that land untapping is primary in green.
