Vallejo Model Colors

Im an acrylic man through and through and use to own a hobby shop here in lil town, Arizona. I still quit a stock of the Vallejo Model Colors and Game colors. My question is, Does any one know a good website that references Vallejo Model colors with other brands. Since I most build Dragon/DML model kits they use Gunze Sagyo as a color base.

I need to find some kind of reference that will allow me to get a good idea of matching GS vs Vallejo. Great models.com has a humbrol color chart you can buy but they are always out fo stock.

Thanks
