If you're like me, you probably don't care for the very odd color scheme this mod uses. To change it, do the following:

---Navigate to the mod's folder, which is:

My Documents > Sid Meier's Civilization 5 > MODS > The Artificers (Brave New World) (v1)

--- Go to [ XML > Civilizations ] and open the file "Civ_Artificer.xml" using notepad (or something similar).

---Find near the top of the file the following line:

<DefaultPlayerColor>PLAYERCOLOR_DARK_DARK_GREEN</DefaultPlayerColor>

And change it to:

<DefaultPlayerColor>PLAYERCOLOR_ARTIFICERS</DefaultPlayerColor>

---Scroll to the bottom to the file until you find "</Civilization_Start_Along_Ocean>"

---Hit ENTER to add a new line and paste in the following:

<Colors>
<Row>
<Type>COLOR_PLAYER_ARTIFICERS_ICON</Type>
<Red>1</Red>
<Green>1</Green>
<Blue>1</Blue>
<Alpha>1</Alpha>
</Row>
<Row>
<Type>COLOR_PLAYER_ARTIFICERS_BACKGROUND</Type>
<Red>0</Red>
<Green>0.75</Green>
<Blue>1</Blue>
<Alpha>1</Alpha>
</Row>
</Colors>
<PlayerColors>
<Row>
<Type>PLAYERCOLOR_ARTIFICERS</Type>
<PrimaryColor>COLOR_PLAYER_ARTIFICERS_ICON</PrimaryColor>
<SecondaryColor>COLOR_PLAYER_ARTIFICERS_BACKGROUND</SecondaryColor>
<TextColor>COLOR_PLAYER_WHITE_TEXT</TextColor>
</Row>
</PlayerColors>

This will change your color scheme to bright cerulean with white trim. Note that instead of your typical 0 - 255 color code, this game uses a strange 0 - 1 code. So black is 0, 0, 0 and white is 1, 1, 1. I don't know what <Alpha> does but it was set to 1 in the base game files (where I took this from) so I'd advise leaving it as it is.
