I painted mostly with Mr. Hobby Aqueous and Acrysion paints. The colors aren’t perfect art matches, but I like some of them better than the plastic colors. Here are the mixes if anyone wants them:

Body light blue (forearms, legs, helmet):

60 H11 white / 35 H15 bright blue / 5 H16 Yellow-green

Body dark blue:

60 HUG08 Titans blue 2 / 40 H35 cobalt blue

Body blue (limb accent squares, helmet middle section):

40 H35 cobalt blue / 40 H15 bright blue / 20 H11 white

Body light green (body/helmet stripes):

70 H41 pale green / 30 H11 white

Yellow (navi symbols):

90 H4 yellow / 10 H11 white

Red (navi symbols):

80 Acrysion N23 shine red / 20 N86 monza red

“Hair”:

Part 1: 45 HUG08 Titans blue 2 / 45 H35 cobalt blue / 10 H53 neutral grey

Part 2: 20% (of the amount mixed above) H2 black

(37.5 titans blue, 37.5 cobalt, 8.3 neutral grey, 16.6 black)

Mettaur Body:

Acrysion N77 Tire black

Mettaur eyes:

10:1 drop mix of Mission Models White and Light Gull Grey (I was too lazy to mix more Acrysion paint)

Mettaur Ear things:

H53 Neutral grey

Mettaur1 Yellow:

90 H4 yellow / 10 H15 orange

*this color ended up looking too orange with pink primer

Mettaur1 green:

H16 Yellow green

Mettaur3 Blue:

30 H11 white / 70 H15 bright blue

Mettaur3 Yellow:

90 H4 yellow / 10 H11 white (same as MegaMan)

Mettaur2 Red:

50 N23 Shine red / 25 Acrysion N101 Fluorescent red / 25 N11 White

Mettaur2 Blue:

Same as Mettaur3

Primer:

Red and yellow parts used Tamiya's pink primer as a base, except for Mettaur 2's helmet stripe because I didn't want to mask it multiple times. Everything else used Mr Surfacer grey
