ESP-IDF Size option question

[username]

In Visual Studio Code, when I click on ESP-IDF size, I see this for my project.
Now my flash app size is: ESP_Foundation_v0.0.bin 843936 bytes
My partition.csv file is:
nvs, data, nvs, 0x9000, 16k,
otadata, data, ota, 0xd000, 8k,
phy_init, data, phy, 0xf000, 4k,
app0, app, ota_0, 0x10000, 3968K,
app1, app, ota_1, 0x400000, 3968K,
#spiffs, data, spiffs, 0x7E0000, 512k,

My question is why is it showing flash code, and Flash data all red, ?
