bar numbers start counting at 1, on the left side of the chart.
this will color the 12th and 18th and 23rd bars on the chart, yellow.

Code:
input bar1 = 12;
input bar2 = 18;
input bar3 = 23;
AssignPriceColor(if (bar1 == barnumber() or bar2 == barnumber() or bar3 == barnumber() ) then color.yellow else color.current);

i made my first study, in post#2, to be exactly as you worded your question.

but, i'm guessing that isn't what you wanted. i usually don't guess at what someone wants, but i had some ideas in my head so i made the following.
maybe it's closer to what you wanted or maybe someone else can use it.


based on you wanting to set something to many days, i had a feeling you wanted to have the bar count start over each day, and look for bar numbers 12,18,23 on every day ? for x number of 'days back' , from the current day.

--------------------------

find up to 6 bars, per each day. the bar count resets to 1, on the first bar of each day.
..defaults, 12,18,23. set number to 0 to disable it.
can pick how many days back from the current day, to look for bars.

a light blue warning label will pop up if,
..a bar number is more than the quantity of bars in a day (normal trading hours).
....the quantity of bars per day is displayed in the label.

..the days back number is more than the days on chart.
....the quantity of days on the chart is displayed in the label.


yes/no options:
..display some stats in labels
..change bar color to yellow
..draw arrows
..draw a hollow box around the bar
....make it a solid box
..display the number above the bar
..draw vertical lines, between each day

look back 3 days from the last bar

close up of 1 day
this shows 4 options,
vertical line between days,
yellow box outline,
arrows,
bar number above the bar

notice the blue arrow on the far right.
on the current day, the arrows will show up under all the desired bars,
even if the bar hasn't been drawn yet.
