Well, it seems time for a bit of Wochenendklugscheißen (roughly: weekend knowing better)!
While there are some tendencies when it comes to genetic looks, the genes expressing hair-, eye- and skincolour are independent of each other and unlike "common knowledge" are expressed by the combination of several genes. Some, like e.g. SLC 2045 or MATP, have more impact than others. That some distinctive "looks" developed is areal evolutiion over time.
My ancestors for instance developed light skin and lactase persistence since in Central and Northern Europe these are evolution advantages. To this day darkskinned persons in Europe have problems with Vitamin D production. And the ability to digest milk and milk-products your whole lifetime came in very handy during famines, bad weather and epidemics. It is actually one of the example genes for selection pressure and advantage. Just one T13090 gene is enough for significant lactase persistence and the mutation spread throughout central and northern Europe in the blink of an eye from an evolutionary timescale. The survival effect was this strong.
Under the glaring sun of Africa people did need dark skin against the rays from the sky and few genetic new expressions survived there due to several factors. When the ancestors of all non-sub Saharan people left Africa, they came into very different lands where different evolution factors and founder effects made themselves known. The Europeans and Asians developed lighter skin, blue, grey and green eyes popped up (according to newer research eye colour shows some subtile effects on your body, it is quite possible that one day your natural eye colour will be part of your medical data), those living at very high altitude gained the ability to carry more oxygen in their blood and so on.
While the evolution pressures, time gone by and founder effects were reasons why we associate certain looks with specific regions of Earth, it does not make variance impossible. For instance, in New Guinea and other regions where Melanesians live, dark skinned people with natural blond hair are a stable minority, not super common, but also not totally unusual.
Going back to our game, if Jasmine and Cornell have afro-American ancestry, which has a quite different admixture than sub-Saharan ancestry, then her having natural blue eyes is far from impossible.
