A bug report was received on the Japan Forum stating that when an image with a color profile embedded that differs from Illustrator's color settings is placed by drag-and-drop, the color values of existing objects are changed.

Here are the steps to reproduce the problem.
Save the image with Adobe RGB (1998) embedded as an example.
Specify sRGB in Illustrator's color settings and set a color management policy other than "None".

Under the above conditions, when an image file is dragged and dropped onto a document, the color values of the existing objects are changed.
This behavior may be a "bug" or a "specification" that needs to be discussed.
By undo and redo after placement, the color values of the group of objects returned to the values before placement.
Therefore, we can conclude that this is a bug.

Although the phenomenon was reported in the latest version 2022 (26.0.3), it seems to be a bug that has existed for a long time.

We will make every effort to alert the community to this issue, but we are requesting that the specification be improved.

タイトル：カラープロファイルの一致しないファイルをドロップ配置すると既存オブジェクトのカラー値が変化する

Illustratorのカラー設定と異なるカラープロファイルが埋め込まれた画像をドラッグ＆ドロップで配置したとき、既存のオブジェクトのカラー値が変化してしまう、という内容の不具合報告がジャパンフォーラムに寄せられました。

再現手順を示します。
・画像には一例としてAdobe RGB(1998)を埋め込んで保存
・Illustratorのカラー設定ではsRGBを指定、カラーマネジメントポリシーの項目は「なし」以外を指定

以上の条件下で、ドキュメント上に画像ファイルをドラッグ＆ドロップにて配置すると、元からあるオブジェクト群のカラー値に変化が発生します。RGB、CMYKを問わず発生するようです。
この挙動について「不具合」か「仕様」か審議を要するところですが、
配置後に、取り消し、やり直し を行うことで、オブジェクト群のカラー値は配置する以前の値に戻りました。
よって、バグと断定できます。

現象の報告は現在の最新バージョンである2022（26.0.3）で確認されましたが、有志で検証したところ、ずっと以前から存在しているバグのようです。

コミュニティでの注意喚起に努めますが、仕様の改善を求めるものであります。

This has to do with repeating patterns. I'm using Adobe Illustrator 2021, desktop.
Attached is a picture of 2 circles on a background (shield your eyes, it isn't pretty :-)). When I make the pattern - in this case, the circles were drawn with the blob brush - the inside of the 2 circles is empty and we can all see the background. It's a ring. When I pull that pattern out of swatches, however, it will color in that background. In this one, it's black. It changes depending on the pattern and the colors I'm using. And it is not consistent. Sometimes it happens, sometimes it doesn't, and sometimes it happens to just some motifs in a design and not others.
After countless tries to figure out what it is, it does appear to be that patterns saved to Adobe's Creative Cloud will have this happen, whereas if I save it to my computer, it will not. Thank you for the help!

Problem: create a square with stroke=0 and fill=100% black. Copy and paste into new document and color swatches are okay. Now go to first document and add a Global Color swatch (i.e. Pantone Green) but don't add it to the square (so it's still stroke=0 / fill=100% black). Copy the square and paste it into a new document. For some reason, that Global Color (Pantone Green) swatch is added to the swatch palette of the new document. Now choose 'Select All Unused', the Pantone Green is selected to prove it's not being used in the element (square) you copy/pasted from the first document.

Add to this: Add another Global Color (Pantone Purple) to the first doc but don't add it to the square. Copy/paste into another new document and only the second color swatch (Pantone Purple) is added to the new document.

Now: Delete the first Global Color (Pantone Green) in the first doc. Copy/paste the square and add it to still another new document. You'll see a color swatch added called 'Deleted Global Color (Pantone Green)'.

I just noticed this bug and posted it in the forums. Another user confirmed they see the same issue dating back several versions. This can be quite a problem when trying to move elements from one document to another.

The Theme Color Picker doesn’t work when...
In a document with artworks and images,

1. Select artworks and click the Recolor icon, then go to Advanced Option.
2. Enable [Open Advance Recolor Artwork dialog on launch]
3. Quit Illustrator
4. Open Illustrator
5. Select artworks
6. Click the Recolor icon in Control Panel
7. Disable [Open Advance Recolor Artwork dialog on launch]
8. Close the Recolor Windows
9. With the Artworks still selected
10. Click the Recolor icon in Control Panel again
11. Click the Color Theme Picker
12. Click on an image in the document

Results: Nothing!

To make it works again, we need to close the illustrator application and reopen it.

This is in 2021 and also 2022.

If you create a new global color swatch, regardless of the breakdown, the name "Black" is automatically blocked. The name "White" is not.

It seems silly to call this issue out, but I've prepared logo libraries for eight and a half years now, and this has been an ongoing consideration. When I create a black swatch, there is always an extra step. Sometimes I intentionally misspell the name to create the swatch, or I create a non-global swatch with the correct name, but in both scenarios I have to adjust the swatch AFTER it is created to produce a black global swatch with the name "Black." The same extra step is not required for a white global swatch with the name "White."

A comparison of my workflow below—

Black Global Swatch:
1. Remove all swatches from the file
2. In the Color palette, click the 'Black' color shortcut
3. In the Swatches palette, either click the 'New Swatch' shortcut at the bottom or select "New Swatch..." from the menu
4. In the New Swatch dialog box, change the default name (depending on color mode, either "R=0 G=0 B=0" or "C=0 M=0 Y=0 K=100") to "Black"
5. Check the 'Global' checkbox
6. Select "OK"
7. No swatch appears in the Swatches palette

White Global Swatch:
1. Remove all swatches from the file
2. In the Color palette, click the 'White' color shortcut
3. In the Swatches palette, either click the 'New Swatch' shortcut at the bottom or select "New Swatch..." from the menu
4. In the New Swatch dialog box, change the default name (depending on color mode, either "R=255 G=255 B=255" or "C=0 M=0 Y=0 K=0") to "White"
5. Check the 'Global' checkbox
6. Select "OK"
7. A "White" global swatch appears in the Swatches palette

Hi all.
Since I was asked by one of the Adobe employees, here's my post.
Windows 10.

I am getting seriously miffed. After using Illustrator ever since the nineties I can no longer do what I need so, so often: duplicating a color stop in a gradient while keeping the other stops as they are.

Say I have the following:

Stop 1 - position 0 - Opacity 0
Stop 2 - position 25 - Opacity 100
Stop 3 - position 75 - Opacity 100
Stop 5 - position 100 - Opacity 0

I need a zero opacity stop on position 50 and 'Alt-drag' the stop on either 0 or 100 to position 50 to copy it.
This always worked, but no more.
Instead, in the latest version it removes the opacity values from every stop it passes.

If I 'Alt-drag' an opaque stop the same happens, all stops that used to be transparent are now fully opaque.
It sometimes even affects stops in the vicinity, sigh.

I can't work like this. I mean, I know workarounds, but I simply want to get on and work normally (fast). Can we hope for a speedy fix?
