Pandaria Inscription

Thank you SpectralDaisy. Hopefully this quick link to Lorewalker Huynh will help too.

For anyone struggling to start Pandaria Inscription you actually need to go to [npc=56065] or [npc=62327] in Jade Forest.
You can't talk to [npc=65716] at lower levels, you need to go to Jade Forest.

This can be trained from Lorewalker Huynh in the Seat of Knowledge in Vale of Eternal Blossoms. *Please note that this trainer is not near a bank has no ink trader nearby, so you will have to come prepared or shuffle back and forth between here and your faction hub.*

When you train Pandaria Inscription, you will automatically learn Research: Ink of Dreams. You will then be able to pay to train at 1/75:

Ink of Dreams
Starlight Ink
Scroll of Wisdom

Everything is orange when you train it.

(I am assuming that Songs of Peace would not have been available to me if I had not already known Legion Inscription. It is trained from this vendor, but it is listed under Legion Inscription, and it is crafted with Roseate Pigment.)

The inks both turn yellow at 10/75, green at 15/75, and grey at 20/75.

At 15/75 you are able to train the follow, all of which start out orange but are grey by 25/75:

Crane Wing Inscription
Ox Horn Inscription
Tiger Claw Inscription
Tiger Fang Inscription

I didn't do research until 20 when ink no longer had a chance to provide skill gain & discovered the following:

Glyph of the Sun for Druid
Glyph of Deluge for Shaman
Glyph of Lesser Proportion for Hunter
Glyph of Pillar of Light for Paladin
Glyph of the Val'kyr for Priest

Glyph of the Sun was orange when discovered between 20 & 25, but the rest were all immediately grey as soon as they were known. I assume it being orange was a bug, though, because I made it twice & neither time gave a skill gain even though it is orange.

Scroll of Wisdom can only be made once a day, so you are left with only doing the Research for skill gain.

At 35/75 you can train making 5 staves and 3 fans:

Inscribed Crane Staff
Inscribed Jade Fan
Inscribed Red Fan
Inscribed Serpent Staff
Inscribed Tiger Staff
Ghost Iron Staff
Inscribed Fan
Rain Poppy Staff

All of these show as orange, but the material requirements for crafting make these prohibitively inefficient for consideration in leveling unless you happen to have the materials and want the transmog. Like other tiers of Inscription, Research is kind of the only option for leveling even when you have nothing to learn from it.

At 45/75 the Ghost Iron & Rain Poppy staves and Inscribed Fan turn yellow (green at 50, and grey at 55), and you can train the following shoulder inscriptions:

Greater Crane Wing Inscription
Greater Ox Horn Inscription
Greater Tiger Claw Inscription
Greater Tiger Fang Inscription

At 50/75 you can train the following shoulder inscriptions:

Secret Crane Wing Inscription
Secret Ox Horn Inscription
Secret Tiger Claw Inscription
Secret Tiger Fang Inscription

At 55/75 you can train Runescroll of Fortitude III which is orange but makes a now useless grey item.

Research turns yellow at 70 and green at 72. There is nothing else to learn but the following once you reach 75/75 skill:

Chi-ji Kite
Origami Crane
Origami Frog
Yu-long Kite
Darkmoon Card of Mists
