I'm pale and have a cool/dark complexion. May be an idea to take her to a make up artist for a consultation about what colours suit her! She may be warm/light, warm/dark, cool/light, cool/dark.
I only do subtle contouring, I don't like the painted on, overdone look. This is what I use:
I use: • max factor - fair 100 foundation
• the lightest powder (that matches my foundation - differing brands)
• to contour, I simply use a powder shade darker (not too dark! Just one, max. two shades)
•a cool, berry coloured blush
•a very light coloured, shimmery highlighter
•a cool brown eyeshadow powder for my eyebrows
-I don't use a bronzer, because warm tones don't suit me
