8 – CKEditor strips all inline CSS and some tokens

I’m trying to add a color and font size to some text using the CKEditor. As soon as I save it these are stripped out.
I’ve also noticed some tokens are stripped down when certain settings are enabled.

I went to add a bit of text in a different font and color but when I saved it and viewed the text the spans were stripped of their “style” tag.
I went to config/content/formats/manage and enabled Limit allowed HTML and added span to the list like so :

<a hreflang href> <em> <strong> <cite> <blockquote cite> <code> <ul type> <ol type start> <li> 
<dl> <dt> <dd> <h2 id> <h3 id> <h4 id> <h5 id> <h6 id> <img src alt data-entity-type data-entity-uuid> 
<u> <s> <p> <h1> <pre> <table> <caption> <tbody> <thead> <tfoot> <th> <td> <tr> <span style>

After saving this all the attributes inside of span are still stripped. I also noticed that many of the tokens I was using (such as site:url) are broken and only half of it remains.

I went back and disabled the Limit allowed HTML option and then when I saved the text the styles and token would save properly.
When viewing the text in an email, the tokens had worked just fine but the span had it’s css striped.

I’ve tried looking for an answer but most are saying I need to enable and add the span to the limit html option but this definitely does not work for me.

There is also Correct faulty HTML enabled, would that be a problem for this?
How can I enable in line styling with the CKEditor?

flash: what are these color strips for?

They are gels to color the flash. It is used for creative effects or to combine with the color of ambient lighting.

CTO (temp orange color) is to match the flash with incandescent lights or sunrise / sunset.

CTB (blue) is to be combined with colder sources (cold LEDs, shade, etc.) … originally intended to change tungsten sources to daylight, so it is not used to correct much with flashes

CTG (green) is used to combine with fluorescent lighting … but these days the color of fluorescent tends to be much better and not so much is needed.

Will the glucose meter strips be safe in the plane's cargo hold?

I will take the glucose meter strips and I need to know if they will be safe in the cargo area.

Possible cause of damaged images (colored strips with dots in the images)?

I've noticed the artifacts / data corruption below (colored stripe with dots) in a small handful of my photos, and I'm trying to figure out the cause. Is it the camera (Nikon d90)? Could it be the SD card or my storage device? I suspect it is not storage (either SD or SSD), because it happens in the same location in different photos.
