I've been using Krita to color some architectural elevations for about 1 week. Maybe I'm not understanding the digital art process, but, I've been trying to use the same color for say, brick, but I won't necessarily color all of the brick at once. I may work on one area, then go to another, while working in other layers. Then if I go back to the brick layer, the color I used previously is not associated to the brick layer from before. If I use the eye dropper to pick up the brick color from before, the color is different. Not sure what that is about either....seems like it should be the same color. The main question is, is there a way to lock a color to a layer so that it is always associated with that layer?

Sorry, no.

Huh. Might want to consider that for future releases

Thanks.

What you likely want is a palette, you can make one with your desired colors or use some of the included ones in Krita, if not on the dockers already, just go to Settings > Dockers >Palette, there you can quickly pick same color over and over as needed.

The popup palette holds color history, up to the last twelve colors used, may not be sufficient though depending on how many colors you use.

Is odd you can't pick the same color, maybe you are using a brush that has a mix or smudge and thus a gradient and or opacity will change the color you originally placed on it. Note that same goes for the layer, if you modify the layer's blending mode or opacity, the eye dropper will pick what's visible.

At times, people (me included) just do a quick "dirty" palette right on the canvas, like in a corner or the layer with the original color with a full opacity brush, a easy way to get back to it specially when the color was randomly picked from the color selector wheel (or triangle/square depending on your settings).

There is many ways to achieve color history, your idea is interesting though, but that would only work if you are using color per layer, which is not as common, also you can check the Krita manual right on the website, will give you plenty of ideas on how to achieve a good workflow, cheers and welcome to the club

Quiralta's suggestion of using a colour palette is a good one and there are three ways of doing it, as noted in the post. If you're using a tablet and stylus to paint then there will be opacity variations no matter how careful you are to press hard on the tablet (which is tiring anyway) so this may be why you get colour variations across an area.

You can edit the brush settings to give constant maximum opacity by disabling the Pen Settings check box on the opacity parameters window. I suggest you do this carefully on only one brush such as the Basic_circle if you do it at all. Then there will be no opacity variation with stylus pressure. This may be confusing for you if you've only just started using Krita.

There is a way to 'lock a colour to a layer' in that painting on the layer will always produce the same colour. This method is to use a Fill Layer, underneath your lineart work. If you choose the Fill Layer properties to be a colour of your choice, you will notice that the painting colour selector for that layer is then limited to the black/grey/white spectrum. This is because by painting, you can only affect the built-in transparency control of the Fill layer. This is similar to a Transparency Layer but it doesn't show on the Layers docker because it's an integral part of the Fill layer.

Then, from the Toolbox, select the Fill tool and make sure the Tool Options has only the 'Limit to current layer' tick box selected. Then click anywhere on the Fill layer and it will become transparent because all of its built in transparency control has been painted black. (Make sure it's a full black 0,0,0 by using the colour slider controls.) After that, you can paint in white on the Fill layer to make it opaque and show its colour. You can do this for many Fill layers stacked on top of each other, painting in white on each Fill layer for different regions of your lineart. However, you still need to make sure your brush has no pressure sensitivity if a consistent opacity or colour shade is important to you.

The advantage of this method is that you can right click the Fill layer at any time to change it's properties, which are either a colour or a pattern of your choice. Then, you can quickly apply different colours or patterns to areas of the final work by changing the properties of each Fill layer that you use. Again, this may be a bit confusing if you're a new user but it is possible and not all that complicated once you get to know it.
