cmyk – 4 color prints scanning

I recently got a poster scanned that sized over 218 mb, it was really a huge size. I discovered that while scanning it had pixels with CMYK 4 color process colors intact. So my question is that, is there any way to get rid of them, and convert them into RGB?

Dress color for fiesta theme background

My background is full of bright colors like a fiesta theme. So what color dress should I wear so that I get highlight in a photo along with background.

photo editing – Underwater: Pure picture with color grading or separated layers?

As I really enjoy underwater photography, I am wondering how does one end up with a final image like the one I share bellow:


Original Image

After Edition:

After Edits


As Lightroom doesn’t have a Channel Mixer (which would be really helpful), I am wondering that the photographer is probably using Photoshop or GIMP. Here the photographer can copy a blue/green channel and convert it to red.

Then it can proceed to the Editings in Lightroom (which is already good for editing pictures at the surface, as one doesn’t looses the colors as underwater).

I know that Tint can also be used for photos less than 10m deep, but it is not the best alternative.

However, in this case, it seems that the photographer is using two separate layers and adds the people separately, so that he can get a darker background.

How does one end up with an image like the one shown above after effects?

Is this only pure picture and color grading?

Color cell background automatically if value has changed from original

Is it possible to automatically color cell backgrounds if their values has been changed (in my case, the only time a cell changes value is by manual user edit/input – no cell values are computed of functions of other cells)?

unity – How to set the color of a game object as of the other?

The class Color has a couple predefined colors, but no color named “player”. And the player itself doesn’t have a color either. The player has a SpriteRenderer which has a color.

So what you need to do is obtain the SpriteRenderer component of the player and then the color from that SpriteRenderer.

 mySpriteRenderer = GetComponent<SpriteRenderer>();  
 playerSpriteRenderer = player.GetComponent<SpriteRenderer>();  
 mySpriteRenderer.color = playerSpriteRenderer.color;  

Further, if you want the sprite to change color when the player changes color, then you shouldn’t put the code into Start, you should put it into Update. This will update the color every frame. A more elegant and performance-friendly solution would only update the color when it actually changed, but that would make the above code a lot more complicated. So I would recommend to do it this way for now to get started.

color management – Windows 10 v1909 Loads Laptop Monitor’s ICC Profile For External Monitor

I have a brand new Sager NP6855 Windows 10 Pro v1909 laptop with an Intel i7-9750H CPU that has integrated Intel UHD 630 Graphics. An external Viewsoinic 1920 x 1080 monitor is connected via HDMI to the laptop. I have been doing color management for over 8 years and I understand the topic very well. I use Windows 10’s control panel Color Management app to assign ICC profiles to the laptop’s monitor and to the external monitor. I make these ICC profile assignments with the laptop video in the Extend display setting. I can see both ICC profiles, they are assigned to the correct displays, and everything works as expected.

As soon as I change the video display setting to either “Second screen only” or “PC screen only” Windows 10 thinks that the external monitor is Display #1 and assigns the Display #1 ICC profile to the external monitor. The problem is that Display #1 is the laptop monitor, not the external monitor. When I launch Settings> System> Display and click on “Identify,” the external monitor is identified as Display #2, which is correct. However, when I launch the control panel Color Management app and click “Identify monitors” the external monitor is identified as Display #1. I believe that because the control panel Color Management app reports the external monitor as Display #1 that that’s the reason that the laptop monitor’s ICC profile is being assigned to the external monitor, which is Display #2. This prevents me from using the correct ICC profile on the external monitor, which is where I do 99% of my work.

Has anyone seen this problem? If so, what did you do to fix it? I’ve read that Microsoft released KB4505903 to fix some of these issues prior to the release of v1909. According to articles I’ve read, the fixes offered by KB4505903 are supposed to be present in v1909, therefore I haven’t downloaded and applied KB4505903. Is there a Microsoft fix for this problem or maybe a third party app that takes ICC profile management completely away from Windows 10 (which I would be THRILLED to use!).

Thanks In Advance For Your Help!

I am trying below code which i picked from stack only i am using this code to change color of selected item its working fine but i also want to set color of first element always selected once page load

                        var List = React.createClass({
                          getInitialState: function(){
                            return { active: null}

                          toggle: function(position){
                            if ( === position) {
                              this.setState({active : null})
                            } else {
                              this.setState({active : position})

                          myColor: function(position) {
                            if ( === position) {
                              return "blue";

python – Network color map based on road length (Pyhton, osmnx, networkx)

Currently, I have a plot that shows all the shortest paths between all the nodes in my network and my target: enter description of image here

Now I would like to make a color palette, where I would color the original nodes and edges depending on the distance from the shortest path. Can anyone help me?

Here's what I have:

import networkx as nx
import matplotlib.pyplot as plt
import osmnx as ox
import pandas as pd
import geopandas as gpd
from shapely.wkt import loads as load_wkt

ox.config(log_console=True, use_cache=True)

place = {'city': 'Lisbon', 'country': 'Portugal'}
G = ox.graph_from_place(place, network_type='drive')
G = ox.project_graph(G)
hospitals = ox.pois_from_place(place, amenities=('hospital'))

hosp_1 = hospitals.iloc(21)('geometry')  # Hospital Santa Maria (Polygon)

def poly_centroide(polygon):

# Gives me the coordinates of the center point of the Polygon

    p1 = load_wkt(polygon)
    centroide = p1.centroid.wkt

    return centroide

polygon_1 = str(hosp_1)

coord_1_str = poly_centroide(polygon_1)

coord_1 = (38.74817825481225, -9.160815118526642)  # Coordinates Hospital Santa Maria

target_1 = ox.get_nearest_node(G, coord_1)

routes = ()
for node in G.nodes:
        route = nx.shortest_path(G, node, target_1)
    except nx.exception.NetworkXNoPath:

fig, ax = ox.plot_graph_routes(G, routes, edge_linewidth=0.2, node_size=5, route_linewidth=1)

Now I would like to know how to create the cmap where the colors of the nodes and edges are based on the distance of the shortest path.

I wonder if it could be done with nx.draw() but I do not know how …

Thanks in advance.
