Hair Color for True Autumn
True Autumn is the season hair color was invented for. This is the one place in the whole system where you can go warmer than feels sensible and it keeps working — copper, auburn and gold all sit naturally against this coloring rather than reading as a dye job.

Professional dye is coded level-dot-tone. Level is 1 (black) to 10 (lightest blonde); tone is the digit after the point, standard across brands.
Your tones are .3 gold, .4 copper, .5 mahogany and .6 red. That is a wider warm range than any other season gets, and it is why True Autumns can carry a genuine copper that would look costume on almost anyone else.
Your range is level 5 to 7 — medium brown through dark blonde, always warm. Codes that work read as 6.3, 6.4, 7.3, 5.4. Note the difference from Dark Autumn, which sits two levels deeper: same warmth, less depth.
Ash is the enemy. A .1 tone is blue-based, and blue against a fully warm coloring produces the specific muddy grey cast that makes people say a color "went flat after two weeks."
Sun-lightening suits this season in a way chemical lightening often does not, because it lifts warm. If you want brightness, ask for warm-toned highlights a level or two up rather than a global lift.
What to ask for at the salon
What to say at the salon. "Level 6, gold or copper base — a 6.3 or a 6.4. No ash toner at the end."
The last clause matters. Plenty of colorists finish with an ash toner by default to neutralize warmth, which is correct for most clients and exactly wrong for you. Say it before they mix, not after.
If you are going red, .6 at level 6 gives a natural auburn rather than a fashion red. It grows out without a hard line because it is close to where your hair already sits.
TODO before launch: verify and name 4 to 6 current shades across two brands that match levels 5-7 in .3/.4/.6. Do not publish invented product names.
