There are two separate genes involved. One is Tangerine on chromosome 10 in Jaune Flamme.

The other is Beta Carotene on chromosome 6 in 97L97.

The key difference is that Tangerine is from interrupting the lycopene biopath. The tangerine color is from accumulation of prolycopene which gives a rich orange color. When heterozygous with a normal lycopene gene, prolycopene is converted into lycopene which is red. Therefore a cross of Tangerine X Lycopene always produces a red Lycopene fruit.
Beta Carotene is different in that it is a parallel biopath to lycopene. You can get both lycopene and beta carotene into the same plant. Caro Red is just such a plant with both beta carotene and lycopene in the same fruit. The result can vary from pale reddish orange to rich orangish red. Caro Red!
