How to change colour of an object

[enginestar]

I have an object - simple graphic - it's just a shape.

What's the best way of changing its colour?

Paint bucket is hit and miss. It seems to overfill and add bits that weren't there before.

Just wondering if there was a better way?

Thanks

(Using older version of Affinity.)

Are you using Affinity Designer, Photo, or Publisher?

Is the "simple graphic" a Vector object or a Pixel layer?

Assuming you are using Photo and it is a Pixel layer you may want to turn down the Tolerance in the Context Toolbar for the "Paint bucket" to avoid the overfilling. Another way is to use an Adjustment layer called HSL to change only the Blues (or yellows, or browns, or pinks etc) to something else. Then there is the Recolour Adjustment layer which will recolour everthing.

If it is in fact a Shape that is a vector then select the vector shape and call up the Colour Panel and choose a Fill colour.

@Old Bruce Ah..., yes some vital info missing in my question. Apologies.

I use Affinity Photo.

The object isn't a vector object (it should be though). In the Affinity Photo file i have it's a pixel layer.

HSL: just seen a video on that. Awesome 👍🏼 

BUT... I'm finding it impossible to get pure red. What should I do here? I can get loads of other colours - but not pure red (and I would assume others)

Recolour layer: I searched around and can't find that one. I found some where you make a selection and then mask and then choose recolour - I guess that's what you mean? HSL would be preferred in that case

EDIT: I just discovered recolour near HSL in adjustment layer.

EDIT EDIT: one version I need is white. So I make the graphic white and add a black background rectangle - the recolouring or HSL ALSO applies to the layers below. How do I fix?

Would still like some feedback if I've done anything wrong above. Thanks.

You may need to use a mask with the Recolour Adjustment layer. On your Pixel layer use the "Magic Wand" Flood Select Tool to select the rectangle, you may need to adjust the tolerance. Now add a Recolour Adjustment Layer, it will create a built in mask so as to only affect the rectangle.

If, and only if, your "rectangle" is a Pixel layer consisting of only the rectangle and no other stuff then a simple Recolour Adjustment layer with no mask will suffice.

It is quite difficult to give advice when I don't know if the "rectangle" is part of a pixel layer with other things on that pixel layer, hence my suggestion about selecting it with the Magic Wand/Flood Select tool.
