Designer displays only grayscales after opening PNG

Recommended Posts

In Designer (1.7.3 on Mac) I've opened a grayscale PNG. The vector shapes that I've drawn over it display only in grayscale, even though the color palette shows them to have RGB colours.

Would be grateful if someone could tell me how to get my vector shapes to display in color.

(Apologies if this has been asked elsewhere – I've searched but cannot find anything.)

Sorry to have wasted anyone's time – I should have looked in File > Document Setup where you can specify the color model. It seems that Designer takes the color model from the bitmap file that it has opened. (Perhaps it would be helpful if Designer gave you the option of color models when opening bitmaps.)

Welcome to the forums.
I’m glad that you found an answer.
I think it might be useful if Designer gave you an option to choose a colour model if the image doesn’t have an embedded one – I think the Assistant gives it a default colour model at the moment – but I don’t think it would be a good idea to have to select one (or accept the current one) every time you opened an image. That could become a bit annoying after a while.

If I open a grayscale PNG, the Color panel clearly shows grayscale by the colors that are displayed:

Is that not what you saw?

Hello Garry – thank you for your reply. I agree – on reflection it would be irritating to have to specify a colour model for each opened bitmap.

Hello Walt – thank you, too. Yes, that's what I saw: RGB colour sliders, but displaying in greyscale instead of (as I expected) in RGB.

I think my confusion arose because, as a new Designer user, I was hoping that most things would work as they do in Illustrator. (I guess if you use that program for over 30 years, you get rather set in your ways!)

Thank you both again for your comments.

You’re welcome.
There are lots of people here – I’m not one of them – who have used Illustrator (and other similar software) for a very long time so you shouldn’t be stuck for answers if you have any further problems moving across to the Affinity applications.

I never use an Illustrator, so just for the sake of interest - does the Illustrator always ask when a picture is opened, what color model do you want to assign to it?

Hello Pšenda: thank you for your question. No, Illustrator doesn't ask which color model to use when you open. But if you open a greyscale bitmap (for example) in Illustrator, and then specify an RGB color to work with, the color displays in RGB, as does the color palette. This doesn't happen in Affinity Designer, which was what I found puzzling (until I realised you had to specify a diffeent color model explicitly).

Illustrator is a very capable vector drawing program, and it still has many really useful features not present in Affinity Designer. But I think AD may be the future of vector drawing. It has already overtaken Illustrator in some important basics (most notably node control), and I look forward to seeing it catch up with Illustrator in other areas.

I think this could be handled by adding a new option to the Assistant.
Situation:
Use opens an image that has a greyscale colour model.
Remedy Options:
(A - default) Convert to an equivalent colour model;
(B) Do nothing.

Users would, by default, get their image converted to colour automatically, while people who like to work with the image’s original colour model could simply change to “Do nothing” and work uninhibited from that point on.

I think that would cover most situations.

This option is already there - Preferences, Color, Convert opened files to working space.

Edit: Although not working as I would expect :-)

Missed that – I don’t have any true greyscale images to test with and didn’t want to convert any in case that somehow messed up the testing.
So that’s the answer, isn’t it? Job done? Or am I forgetting something?

:-( Unfortunately, it doesn't do what I would expect. Obviously it translates only color space/profile, not color format.

It does just what I expect. It converts to the working space's color profile. You have a choice of a different working space color profile for RGB, for RGB/32, for CMYK, for LAB, and for Grayscale. If the document you're opening has color space "X", and it's profile does not match your specified working profile for "X", it converts it.

It really didn't surprise me at all, you know everything.

Just a pity, that it is not described more detailed in the help, because there is nothing written about individual formats at all - "Choose whether to convert an opened file colour space to the working space and also choose whether to warn that this has occurred."

Yes, that Help could be clearer.

In fact, isn't it wrong? To me, color space is RGB vs CMYK vs Grayscale vs Lab, and Photo will never do that conversion upon opening a file.
