Added invalid color

[bofh69]

Describe the bug I added a new filament via the REST API. There I gave it the color "#FF000000". I got a "500: Internal Server Error." message back.

After that the GUI no longer worked, it would complain about an internal error.

The logs say the string is too long:

To Reproduce

Create a vendor, then create a new filament with the following json-data:

{
    "name": "PolyTerra Charcoal Black",
    "vendor_id": 1,
    "material": "PLA",
    "price": 20,
    "density": 1.24,
    "diameter": 1.75,
    "weight": 1000,
    "spool_weight": 140,
    "article_number": "PM70820",
    "comment": "",
    "settings_extruder_temp": 210,
    "settings_bed_temp": 60,
    "color_hex": "#FF000000",
    "extra": {}
}

Ie putting the data above in test.json and running:

wget --header="content-type: application/json" --method=POST --body-file=test.json http://localhost:7912/api/v1/filament

Expected behavior I would expect the filament creation to fail with an error message. I would also expect the field with the invalid data to be cleared when reading the data from the database.
