Represented in black and white when selecting colors in gradient tools.

[#1]

Applying gradient to an object basically allows it to select two colors. If I choose one color by using color picker from there, it expressing in black and white in the gradient. If I reboot the program or return from another operation, express the correct color for the previous operation again. Usually, the program needs to be rebooted before it can be resolved. What's the matter with this?

Can you perhaps post screenshots and describe this step by step.

1) A rectangle. That is an example object.

 2) Select Gradient tool and applying

3) Editing color at right side with Color Picker

4) Result. Red is expressed in gray.

In addition, this problem seems to occur randomly. Or maybe I'm not good at using tools.

Check that your colour mode is not set to grayscale:

Thank you for your answers. This temporarily solved the problem mentioned. However, if I close the program and turn it on again, then apply the gradient, it will be expressed in black and white mode again. Is there no way to set the default value by RGB mode?

The default gradient is back and white.

Don't use the color picker (for several reasons).

Just use the gradient panel or the gradient annotator to define colors.

I see. Thank you all for your replies.
