What is red, orange, yellow, green, blue and purple jam?

Common paper jams that meet the requirements of the topic are as follows:

Red jam: strawberry jam and watermelon jam.

Orange jam: orange jam, apricot jam.

Yellow jam: lemon jam, loquat jam, peach jam, kiwi jam and chestnut jam.

Green jam: green kiwi sauce

Blue jam: plum sauce (in fact, the color of plum sauce is slightly lighter than blue. )

Blue jam: blueberry jam (actually, the color of blueberry jam is mixed with some purple, not pure blue. )

Purple jam: plum jam and grape jam.

In the process of cake processing, there are also jams that add food pigments (or natural raw materials such as coconut milk and chocolate) to realize full-color series (including metallic colors such as gold and silver) and make them decorative. They should not be discussed here.
